Hello:

In the past few days we have experienced multiple stability problems with clamav. Here is our environment:

Solaris 9 (sparc)
mimedefang 2.36 w/ sendmail 8.12.10
clamav 0.65



Isn't 0.65 known to have problems? I use daily snapshot (devel-20040115) and it works fine so far.

This was submitted to [EMAIL PROTECTED] yesterday... just curious, is there any type of acknowledgment that we should expect from such submittals?



Some acknowledgments are in ChangeLog.

Here is an example of the problem from today. The previous entry in the log was from an hour earlier and all was OK. We discovered freshclam had died (with no notice sent) when we were preparing the documentation for the clamd problem. We received no notice that freshclam had any problems or had died.



I use freshclam -d on Solaris9, and it didn't die during "Malformed CVD header" period.

CLAMD PROBLEMS:
===============
Yesterday, just before 11:00 we started getting all sorts of 'strange' mimedefang errors -- none of which were 'problem running virus scanner'. Checking, we found that clamd was not running. (We use clamdscan in mimedefang, not clamd directly, as it appears to be somewhat better at catching some viruses.)


Notice that it appeared to die the first time shortly after finding 'Worm.Gibe.F' -- with no indication of why it died. (The virus hit was successfully passed back to mimedefang.)



The problem might be in
"

Mon Jan 19 12:04:37 2004 -> Mail files support enabled.

"

Try commenting ScanMail on clamav.conf. I don't know how stable (or reliable) ScanMail support is now, but since you use mimedefang you wont need clamd to unpack attachments. Disabling it will at least reduce scanning time a little.
