Hi,
firstly, I cant beleive Julian is stil so commitied.
I finally upgraded to mailscanner-4.30.3-1 (from my own heavily patched
3.13 where I helped Julian write the original inoculate code).
Anyway, I love 4.30, the upgrade was pretty straight forward.
My problem is my inoculate scanning stops working, and is skipped over. I
have 4 virus scanners enabled, and the others keep going.
I assume at one stage or another the inoculate doesnt return like it
should, and it is marked as Busy.
The /tmp flag for inoculate shows it is busy. (see lots of details below).
I do not use the update_virus_scanners, I got rid of it out of cron, but
apparently its not the only code that either locks things in /tmp or calls
update_virus_scanners. Obviously, I am updating signatures myself.
I have Max Children = 1 in the mailscanner.conf. But I guess that Virus
Scanner Timeout = 300 times out on inoculate at some stage and marks it
busy or something.
Clearly when I restart it from init.d it all runs OK again for a while.
I guess what I need is one of these:
- understand why its busy and fix the condition
- get rid of the busy
- more agressively restart mailscanner when the condition occurs / or the
Virus Scanner Timeout times out
- move over to update_virus_scanners if its significantly better.
cat InoculateBusy.lock
