multiplexing overflow errors

[Dieter Stüken]

I'm using rsync 3.0.6 between two solaris 8/10 hosts an I frequently get "multiplexing overflow" errors:

log/20091123_223901/dresden.log:multiplexing overflow 101:7104843 [sender]

log/20091124_193051/muenchen.log:multiplexing overflow 101:7104843 [sender]

I have to admit that I have to syncronize HUGE directories with up to 1 000 000 tiny files!
But this does not fail in general. After a few retries it works, but it is annoying.

Any clue?
I compiled the source myself, so I may be able to debug it or to include some diagnostic messages to narrow the problem.
