The perl process(es) initiated by amavisd + spamassassin
to handle email(s) are very often running up to 100 percent
of both CPUs, and staying there until killed. Then amavisd (master)
spawns another one or two, which each handle perhaps 10 to 20 emails
before
getting stuck once again.
A perl process gets stuck even when the emails are small, under 3K.
An identical text message sent twice from outside will have one get
stuck,
but the other passes correctly. Similar emails can also take a
long time in the SA Check, but eventually
finish, often showing an SA check of around 30,000 ms, (99%).
Typical last entries in the amavis.log read as:
Mar 12 20:58:58 ns1.xxx.com /usr/bin/amavisd[19428]: (19428-05)
Checking for banned types and filenames
Mar 12 20:58:58 ns1.xxx.com /usr/bin/amavisd[19428]: (19428-05)
p.path: "P=p001,L=1,M=text/plain,T=asc"
and then nothing more, till the process is killed.
It seems that $child_timeout in amavis.conf
is not effective.
This is a lightly loaded machine, OS X Server, 2-CPU's 1 Ghz, 1.25 GB
of ram,
at most 1000 emails per hour.
The programs are nearly vanilla unmodified, as installed by Apple.
What suggestions for where to look next?
