An anti-wget conspiracy at apache.org perhaps...! :-) Wesley.

Hi, On Fri, Aug 11, 2000 at 11:16:10PM +0400, Vladimir Buyanov wrote: I have the following problem with Apache mod_perl and MySQL. We have written Web chat server based on: FreeBSD+Apache+mod_perl+MySQL. Hardware: 2xPIII 550, 1Gb RAM Also there are PostgreSQL and exim for other tasks on that machine. We use 2 httpd scheme: one "light" for handling static content (without mod_perl) and another one with mod_perl. First uses proxy to pass requests to /script directory to mod_perl enabled "heavy" httpd - httpd.modperl. I have test program called "Load Emulator" that can send HTTP requests with certain rate. I sends 5 requests/sec to chat scripts. First all things are good. But suddenly httpd.modperl begin to spawn and reach the maximum number of processes that I set - 50. This means that summary memory usage of httpd.modperl processes is about 500M! Fifty seems like a heck of a lot of heavy apaches. Chances are you'd only hit that number when Bad Things are happening and a number that high just makes things worse. What happens if you change maxclients to ... ten, say? Then "heavy" Apache stop to respond to clients - I run my browser and see "Proxy Error". When I stop Load Emulator, such situation continue in about a 5-10 minutes, then httpd.modperl processes begin to die. During this mysqld eats about 5-10% CPU and 140M RAM. Sounds like your heavy web pages are taking too long to generate. I'd be inclined to blame any sql in there - find which queries are taking too much time and tune them. This is probably best discussed on a MySQL list, though... :-) Attempt to free unreferenced scalar. Yeah, we get those too. I don't know what they are either. *grin* Running without perlfreshrestart/graceful-restarts seems to help, but this cure is worse than the disease - we just put up with the slight memory leaks associated with the occasional graceful restart and do a hard restart every week or two. It's only a minor niggle and someday I'll sort it out! All the best, Wesley.
