Public bug reported:
Binary package hint: rsync
On our public free software mirror (also se.releases.u.c) we run amd64
hardy on the frontends. The rsyncd parent process quite often stops
responding to new connections, and during this it seems to spin on cpu
with 100% cpu usage. A quick check with strace on this process doesn't
show any syscalls happening.
We currently have a script in cron.hourly that restarts rsyncd if there
is nothing responding on localhost:: but even then the outages are
frequent enough that it is a problem for our users (especially
downstream mirrors). I would guesstimate at a couple of restarts every
week.
We've observed this bug since dapper/sarge, but it seems to just get
worse, so I'm finally getting around to reporting it. Any suggestions
for tracking it down are most welcome, at least if they can be
implemented transparently on a production system.
