Apache 1.3.29 RedHat Linux 9, kernel 2.4.20-31.9 PHP 4.3.4 MySQL 4.1.7 First all thanks for the tips. I checked the MySQL error logs but unfortunately it is not as verbose as I wish it would be. The /var/log/message tells me the first apache process killed was at 15:10 (so it maxed at that time). So I looked at all the requests from that time up until 15:27 when I stopped Apache. There were continuous requests but I believe these were requests that Apache could serve without the help of the db (this is not 100% checked but it does seem like it) and there seem to be less requests than in usual circumstances. The Apache error log reports nothing unusual. I did get a tip though that a user ran a newsletter-sending PHP script roughly at 14:47. The script has been used many times before and never failed but it does issue many SQL requests. The culprit is probably the MySQL server. --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
