While the blame has been placed on high traffic by those helping to troubleshooting the problem, I have felt that there was something else going on, since most of the crashes we have experienced have actually been random, often at low peak times, and the symptoms are nearly identical to those documented in the bug report. While granted our web traffic has been increasing steadily over the past few months, the beginning of our crash problems was quite sudden, starting after we migrated from RH 7.1 to 7.3 and then updated the kernel. It has been extremely difficult to pinpoint the issue since there are virtual no errors logged when this occurs, and there seems to be little to go on by way of finding a common denominator between the incidents. A 'uname -a ; cat /proc/sys/vm/bdflush' returns: Linux server1.myserver.net 2.4.20-20.7smp #1 SMP Mon Aug 18 14:46:14 EDT 2003 i686 unknown 30 500 0 0 500 3000 60 20 0 A couple questions, first - all of the comments regarding this bug appeared to reference RH9. Does the same apply to RH 7.3? Second, what exactly do these bdflush figures represent, and how does the recommended edit change the behavior of the system. Needless to say I am desperate for a solution, but I am reluctant to make any changes without understanding the potential effect on the system as a whole. ------------------------------ Laurie Harper Dealer ImpactR Systems WWWeb Impressions, LLC 7725 Douglas Ave Urbandale, IA 50322 (515)334-9638 ext.15 http://www.dealerimpact.com http://www.webimpressions.com ------------------------------ This message (including any attachments) contains confidential information intended for a specific individual and purpose, and is protected by law.
