Iam using rsync tool to sync files from one linux server to other linux server, however it takes huge time to finish it. so I tried running multiple instances of rsync for different directories in background and it resulted in the below mentioned error.

rsync comand used:

/usr/bin/rsync -acrz ${ABS_DIR} -e /usr/bin/rsh ${TARGET}:${TARGET_DIR} &

the below error was thrown,

poll: protocol failure in circuit setup
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(463) [sender=2.6.8]

Please let me know whether is it possible to run multiple instances from one server to another server and if it is possible, please guide me...

Thanks

The network connections are fine...

What does the rsyncd.conf file have for max connections?

What does syslog say about errors on the remote side?

There is no rsyncd.conf file, as per my understanding it is needed only when you are running rsync as a daemon (let me know if Iam wrong)

This is what the syslog shows
