amd64 FreeBSD 6.0 problem

2006-05-22 Thread YTResearch

Please let me know if this is not the right list to ask this.

I have a Tyan 4882 4 CPU (dual core) Opteron, running amd64 FreeBSD  
6.0 Release, 8 gig ram (all recognized), SCSI 15K Seagate ST373454LC  
drives. BIOS is running all stock settings.


It's job is to run Apache (ran 2.1 now latest 2.2, have tried  
threaded and prefork configurations).


It runs blisteringly fast and appears to have no problems except one.  
It hangs after running 5 to 7 days, once after 2 days. There are no  
error messages in the log and it just stops responding. The only  
solution is to physically go press the reset button where as it  
recovers perfectly every time (after fixing the messed up any messed  
up file system links).


The system is a very high traffic web server. It services html pages  
and trivial Perl CGI forum software running without any particular  
privilege. Prior to a hurried installation, I ran a high volume bench  
mark against it on my own lan hitting it with 10K of requests for a  
trivial web page look up and did produce a hang but the person  
needing the system really needed it that day. Because of that I've  
tried two versions of Apache and various MPMs all with the same  
result. I think Apache may be a red herring in this. I also  
discovered that it's running off an UPS rated lower than it's power  
requirements though only under extreme conditions, the UPS is being  
replaced this week. The hang seems too consistent to be power but  
perhaps not.


I would like to know if anyone has heard of such an issue with amd64  
6.0 Release and what debugging processes might have been used to get  
around it. I have dmesg and more *stat information if that would help.


Thank you in advance,
Chris

apache probably has nothing to do with this.  Apache shouldn't be  
able to freeze the machine.  That sort of thing happens with marginal  
power, heat issues, HW issues (RAM etc)...
