I have set all limits to extreme, but still I get 503 error after script has processed 15 minutes (900 seconds). PHp does not give any errors. MySQL keeps going.
Debug messages at the exact moment when 503 happens are:
[uds://tmp/lshttpd/lsphp.sock] No Request has been processed successfully through this connection, the maximum connections allowed will be reduced!
[xxx.xxx.xxx.xxx:61621-0#xxxxxxxxxx.xxx:lsapi] HttpExtConnector::tryRecover()...
My test case is repairing (fixing indexes) lots of big tables (7.5 million rows) with latest phpmyadmin using latest Firefox. After the litespeed gives up mysql keeps processsing the command happily under hood.
How should I set litespeed up so that in no case a php script connection is "dropped out" like this? I find all the settings very confusing, if 4000 second timeouts are not honored what should I do?

php.ini has

Took APC offlline, one less variable to debug.
PS. I would like to set different timeout rules for each virtual host (high timeouts for the one I use for admin stuff, low for public site). Because virtual servers do not have individual connection timeout setting I am forced to put high value in server tuning setting and that means less tolerance to DoS for the public site.

) while it was running. I just guessed which PID's to follow.
