Mailscanner max'd out CPU/memory and not processing mail

"Check for hardware faults. Does /proc/meminfo still agree with you on the
amount of RAM in the box, for example?"

Yes.

"What virus scanners are you using?"

F-Prot.  I have ClamAV installed, but don't use it.

'Run "MailScanner --lint" '

root at fatman:/home/tom# MailScanner --lint
Read 759 hostnames from the phishing whitelist
Config: calling custom init function SQLBlacklist
Config: calling custom init function MailWatchLogging
Config: calling custom init function SQLWhitelist
MailScanner setting GID to  (119)
MailScanner setting UID to  (111)

Checking for SpamAssassin errors (if you use it)...
lock.pl sees Config  LockType =  flock
lock.pl sees have_module =  0
Using locktype = flock
MailScanner.conf says "Virus Scanners = f-prot"
Found these virus scanners installed: f-prot, clamavmodule


root at fatman:/home/tom# cat /etc/passwd | grep 119
postfix:x:111:119::/var/spool/postfix:/bin/false

'as well as "MailScanner --debug" to check things out.'

root at fatman:/home/tom# MailScanner --debug
In Debugging mode, not forking...
