rsync - May 2002 - Rsync hanging

Trying to figure out this problem.  RSYNC maybe once a day or so will just
hang and sit there... strace attached to the process produces the
following...  I wonder where the loop is.  Anything I can do to help would
be fabulous.  Most of the time it works fine.  Very strange.

You don't mention what version of rsync you're using.  Version 2.4.6
would often hang when the -v option was used, so if you're using that,
you'd do well to upgrade.

The system calls you cite are normal for that process.  It's the loop in
the wait_process() function, which is a normal end-of-run occurrance.
One of the other 2 processes is probably hung up on a read or write, and
you'd have to look at those processes with strace to see what is going
wrong.
