Hi,
I have a server that's frequently pretty busy during the day, and just
started to notice these messages periodically:
Jun 8 13:35:39 mail01 amavis[28784]: (28784-272) SA TIMED OUT,

Is this a result of the server being too busy to process the request,
or one of the services that it uses, such as a DNSBL, not responding
in time? How can I troubleshoot this?
Yes, the first thing I should do is upgrade perl, and that's in
progress, but hopefully I can work out the small problems until then.
Thanks,
Alex
