Re: Crash problem

Hi

All users are local users and all have quota exceeded. Problem only 
happens when i do a manual

/usr/exim/bin/exim -qq

Queue runners running not from command line does not cause the crash.

It is the default 4.99 with the DBM patch I am running. Running on a 
slackware platform. Queue has 225 messages, not all for the quota 
exceeded users.


added debug_store=yes, this is what I get
