SA 3.1.0 freezing

[Rick Macdougall <ri...@nougen.com>]

Hi,

I'm having an issue with SA 3.1.0 freezing, it will run through a couple 
of users (3 - 10) and then lockup.

The debug log shows

@400000004329b9a03554bf84 [14009] dbg: config: Conf::SQL: executing SQL: 
select preference, value  from userpref where username = 
'munged@clubplus.net' or username = '@GLOBAL' order by username asc
@400000004329b9a0355ced44 [14009] dbg: config: retrieving prefs for 
munged@clubplus.net from SQL server
@400000004329b9a0355ffa84 [14009] dbg: info: user has changed
@400000004329b9a03563619c [14009] dbg: config: score set 1 chosen.

and it just stops there.

stracing the process shows the process just waiting

tmp]# strace -p 14009
Process 14009 attached - interrupt to quit
read(7,

I also always see this in the logfiles
dbg: prefork: sysread(7) not ready, wait max 300 secs

Specs
Redhat ES fully up to date
This is perl, v5.8.0 built for i386-linux-thread-multi
(with 1 registered patch, see perl -V for more detail)

Any one with any ideas ?

Regards,

Rick

We have seen this with a RHEL 3.5 server SMP kernel as well, but the 
problem was not specific to spamassassin, but something on the OS/kernel 
level that not only caused spamd to hang up, but clamav, and even trying 
to send an attachment locally from pine, mail, etc... A reboot would clear 
up the problem, but it would return 3-5 days later. The hangups would only 
be for emails with attachments.

If you see the problem again, let me know, as we are trying to find the 
cause as well. We will be going to a non SMP kernel if the problem appears 
again. You can grep your /var/log/maillog looking for:
grep timeout /var/log/maillog|grep -i local

If you see a lot of timeouts during draining input, this will signal the 
problem re-occuring.

Hi,

BTW, a reboot fixed it but I still don't know what caused it.
