Hi, 

The past week I've had four sarge boxes apache processes lockup.
apachectl restart works without error, but the webservice is still not
responding.  Other methods (killall -9 + invoke-rc.d restart, etc.) are
tried but still, no webservice and nothing in error.log to indicate a
problem. 

Attaching a strace to the apache process, I see that it is in a loop
complaining that /var/cache/apache/__db.ssl_cache.db already exists.
Removing this file and restarting fixes the problem. 

Also I notice in these situations that there are hundreds of ssl.mutex*
files in /var/log/apache. 

Possible DoS attack in the wild?  I wouldn't think so but it's been the same 
thing on four different servers in a week... I'm going to post to some lug 
mailing lists later today to see if anyone else is seeing this.  

Best

Mark
