I'm using postfix 2.7.1 with amavis 2.7.0 as a proxy. After some clients
reported errors sending email, I've noticed postfix is sometimes unable
to relay email to amavis due to 'queue file write error'. I'm kinda
clueless, why... Unfortunately I can't see no logs at that time in the
maillog. Due to this being an active server ( ~100 msgs/minute) I don't
dare starting amavis in debug mode.
Oct 28 15:30:26 smtp-1 postfix/smtpd[3215]: warning: timeout talking to
proxy 127.0.0.1:10024
Oct 28 15:30:26 smtp-1 postfix/smtpd[3215]: proxy-reject:
END-OF-MESSAGE: 451 4.3.0 Error: queue file write error; from=<a...@b.c>
to=<d...@e.f> proto=SMTP helo=<hhh>
I belive the hardware itself is adequate - ibm hs22 blade, dual quad
core xeon with ht, 24GB ram, it's running Centos 5.5 x64. First I
thought there aren't enough running processes of amavis, so now I'm
running 100 instances (was set to 50 before), but guess that didn't fix
the problem.

Any ideas how to start analyzing the problem?
