I don't think it should be complaining to you about it it should just do what the server allows and not bother you with the details , so that's worth reporting to Perforce support as a bug -- they'll want to know what version of the client and what version of the server you're using.
In the meantime, to work around it I'd imagine you can go into P4V's preferences and explicitly disable parallel syncing. You could also have your admin enable the option using the command you got from the error message. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Will the user start another copy job? Rather than invest a lot of time coming up with a low confidence estimate that would be only slightly improved over the current one, we focused on presenting the information we were confident about in a useful and compelling way.
This makes the most reliable information we have available to you so you can make more informed decisions. Many high-volume Windows users today resort to using third-party tools like Total Commander , capable of handling large background file transfers on their own without slowing down the system and without, as Windows Explorer is still prone to do, crashing. This mode supports transfers of small files.
Though it transfers large files successfully between sites in close proximity, it degrades when transporting large files over long distances. There is a drop in throughput that results from two limitations. First, the bandwidth on the lines is limited. Second, the "pipe" between sites is not fully utilized. The sending machine could transmit much more data in the time it loses waiting for acknowledgments. These acknowledgments are checksums returned from the receiver to verify correct delivery of each packet sent.
An ideal transmission would stream data, error free, to arrive as quickly as it is sent, keeping the line fully occupied. In reality, however, much transfer time is wasted, because Internet errors dictate that the operation must transfer the data in very small packets sent in lock step. Each packet has to wait until the previous packet has been transmitted successfully and the successful transmission acknowledged. Thus the transfer has been drastically slowed down. Two prior-art implementations have tried to solve these problems.
This solution, available only by request, requires the server to have the MFTP daemon running continuously. Though the client can be compiled and executed by a system user, the server must be compiled and installed only by a user who has system root privileges. As the MFTP server is an add-on to Unix Internet services, it requires that the Unix operating system be installed and running on the server.
SMFTP provides both one-to-one and one-to-many multicast transmissions. The transmission process is offloaded to a Multicast server that replicates and transmits the data. The transmission window is extended to the entire length of the file. Error correction follows transmission of the complete file. SMFTP also requires the user to install a server as root and various clients who wish to transport to or from the server. Neither of these prior-art solutions is satisfactory. Any security-conscious network administrator will object to the installation of any non-standardized third-party Internet services software for fear of hidden or unknown entry points that can compromise the system.
Thus both these prior-art solutions require that a separate server be installed at every site from or to which the user wishes to transfer data. Therefore they are acceptable only to a distributed commercial organization willing to make such an installation. Thus there exists a need for a solution to the problem of transferring large files over long distances that does not require a proprietary installation.
One object of the present invention is to provide a method for transferring large files expeditiously over long distances. A further object of the present invention is to provide a method for transferring large files expeditiously over long distances without requiring a proprietary installation. Another object of the present invention is to provide a method for transferring large files expeditiously over long distances that makes use of standard and readily available protocols.
Briefly stated, the present invention transfers large files expeditiously over long distances by making use of the FTP application, a standard application native to every Unix workstation. In the apparatus and method of the present invention, the data to be transmitted from a host computer is segmented into separate packets that are transmitted in simultaneous FTP sessions, and the separated packets are recombined at the receiving computer. This log specifies 1 the number of pieces; 2 how the pieces should be ordered when they are combined to form the original after transmission; and 3 the method used to segment the data.
The simultaneous FTP sessions are carried out by a combination of automating each FTP session and processing, that is, segmenting and recombining, in the background. According to an embodiment of the invention, a method for transferring files between remote computers, comprises the steps of segmenting into a plurality of packets a file to be transmitted to a remote receiving system; transmitting the plurality of packets substantially simultaneously to a remote receiving system; and recombining the plurality of packets into the file at the remote receiving system.
According to a feature of the invention, a method of transferring files over a network, comprising the steps of creating a log for a file; segmenting data from the file into a plurality of packets; identifying each of the plurality of packets; recording in the log information to identify each of the plurality of packets and its order in the file; invoking a simultaneous file transfer algorithm at a remote receiving location; transmitting the log to the remote receiving location; analyzing the log at the remote receiving location to identify each of the packets and its order in the file; transmitting the packets substantially simultaneously to the remote receiving location; and recombining the packets into the file.
According to another feature of the invention, a system for transferring files between remote computers comprises means for segmenting into a plurality of packets a file to be transmitted to a remote receiving system; means for transmitting the plurality of packets substantially simultaneously to a remote receiving system; and means for recombining the plurality of packets into the file at the remote receiving system.
According to still another feature of the invention, a method for transferring files between remote computers using the File Transfer Protocol FTP , comprises segmenting into a plurality of data packets a file to be transmitted to a remote receiving system; recording in a log 1 information identifying each of the plurality of data packets and its order in the file, 2 server identification, and 3 methods of segmenting and recombining the file; invoking it a remote computer a client utility effective for simultaneous FTP transfers; transmitting the log to the remote computer; analyzing the log at the remote computer; transmitting substantially simultaneously the plurality of data packets to the remote system using simultaneous FTP; and recombining the data packets according to the information and converting the data packets into the file's original form by means of the methods of segmenting and recombining.
These and many other objects and advantages of the present invention will be readily apparent to one skilled in the pertinent art from the following detailed description of a preferred embodiment of the invention and the related drawings. Referring to FIG.
