[Bug 5120] New: run-away/never-ending message check
http://issues.apache.org/SpamAssassin/show_bug.cgi?id=5120
Summary: run-away/never-ending message check
Product: Spamassassin
Version: 3.1.6
Platform: Other
URL: http://www.hicom.net
OS/Version: FreeBSD
Status: NEW
Severity: critical
Priority: P5
Component: spamc/spamd
AssignedTo: dev@spamassassin.apache.org
ReportedBy: admin@hicom.net
This is a possible DOS attack (at least as far as I am affected).
I upgraded to v3.1.6 since I was getting this problem on v3.0.2
both running Perl 5.8.3 on FreeBSD 4.9, dual P3Xeon-500 intel.
Spamassassin is being invoked from user-specific .procmailrc using spamc/spamd
an user-specific config/options coming from mysql.
I'm getting never-ending spamd child processes. The messages being analyzed are
all types. I have not seen a pattern yet.
Since the never-ending processes eventually use up all available spamd child
processes, eventually no checking is done. I had let 3.1.6 manage the child
processes but it ran out of processes. Both default and explicitly specified
timeout-child did NOT trigger killing of the child pid.
I set the max-message per child to 1 and timeout-child also did not trigger.
I am now running a periodic checker to kill any child pids that exceed 5 mins of
CPU time.

Please attach a sample message that causes the problem. You'll also want to
debug what is going on. running with -D or using strace would be useful.
my first reaction is that you're having a bayes expiry done, which may take a
long time, especially on older/slower hardware.

See bug 4650 comment 2 and bug 3532 comment 7. It really would be good if
the bayes housekeeping were not done by the noramal spamd children.
