Rsync 3.0.5 sometimes hangs copying local disk to other local disk (Solaris 9)
I hope I'm sending this report to the right place.
I recently upgraded the rsync binaries in a bunch of our Solaris 9
systems from rsync 2.6.9 to rsync 3.0.5 . I have a script that runs in
each machine that syncs the file systems from an active drive to a
backup drive. Wihtin 3 days, this script had hung in two of the ~20
hosts that I had updated with the new rsync. Those two hosts happened
to be two of the busiest ones, so very likely files were being removed
and added as the rsync was taking place. I have done an ps -fp on the
rsync processes involved, plus an lsof, a truss trace, and a netstat -na
. The results are in files, each around 30K bytes in size. In case it
helps, I'll include all but the long netstat outputs from one host here.
If someone asks for the full results for one or both of these hosts, I
can send them to him/her. I have never had hung processes with the
older rsync-2.6.9 .
