100% CPU utilisation from time to time

[Tomoiaga Cristian]

Hello,

Some specs:
Intel P4 HT @ 2Ghz
2 GB Ram
CentOS 4.4

I have installed the latest MailScanner package from ConfigServ.
MailScabber almost works fine. The problem is that from time to time I see a
MailScanner process using 100% of CPU. Seems the process is checking with
SpamAssassin when this is happening.

Strace shows something like this:
pread64(18, "\0\0\0\0\1\0\0\0j\10\0\0\0\0\0\0\0\0\0\0\20\1\230\t\0\2"...,
4096, 8822784) = 4096
pread64(18, "\0\0\0\0\1\0\0\0k\10\0\0\0\0\0\0\0\0\0\0*\1\354\10\0\2"...,
4096, 8826880) = 4096
pread64(18, "\0\0\0\0\1\0\0\0l\10\0\0\0\0\0\0\0\0\0\0<\1\200\10\0\2"...,
4096, 8830976) = 4096
pread64(18, "\0\0\0\0\1\0\0\0m\10\0\0\0\0\0\0\0\0\0\0.\1\334\10\0\2"...,
4096, 8835072) = 4096
pread64(18, "\0\0\0\0\1\0\0\0n\10\0\0\0\0\0\0\0\0\0\0J\1$\10\0\2\372"...,
4096, 8839168) = 4096
pread64(18, "\0\0\0\0\1\0\0\0o\10\0\0\0\0\0\0\0\0\0\0004\1\250\10\0"...,
4096, 8843264) = 4096
pread64(18, "\0\0\0\0\1\0\0\0p\10\0\0\0\0\0\0\0\0\0\0L\1 \10\0\2\372"...,
4096, 8847360) = 4096

everything strace shows looks like that and it stops when the process
receives a SIGTERM

Does anyone know something about this ?
Thanks,
