SAVI-Perl problems

[Steve Freegard]

Hi All,

Further to my eariler posting - this seems like a RH9 issue, if I set
LD_ASSUME_KERNEL=2.2.5 in /etc/rc.d/init.d/MailScanner this cures the
problem.

Also - is it still a good idea to set LANG=en_GB in
/etc/rc.d/init.d/MailScanner to speed up SpamAssassin under RH8/9 due to the
UTF-8 issues???

Regards,
Steve.

Hi All,

I thought I'd give the sophossavi interface a try - after doing so, I was
tailing the maillog and noticed that MailScanner was spawning a new child
process every 10-20 seconds or so, and that I had several defunct processes
showing up when doing a 'ps axww'.

I put MailScanner into debug mode and ran it by hand and realised that it
was segfaulting.

Here is the last few lines of an strace:

[root at hoshi root]# strace /usr/sbin/MailScanner

unlink("/tmp/76630000.$$$")             = 0
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
<<SNIP>>

I confirmed that it is SAVI-Perl causing it by changing back to regular
sophos scanning which then stops the segfault.

I'm running this on a Compaq Proliant DL360 1x933Mhz 512Mb RAM running
RedHat 9, MailScanner 4.14-9, Sophos 3.67 and ClamAV 0.54

Anyone else had a similar problem or know how to fix this??

Kind regards,


Steve
