Re: Re: Really odd PHP problem

OK, the situation seems a lot more stable with Zend Accelerator instead of mmcache, and we're regularly getting quite a few "checksum failed" errors in the logs, which does tend to indicate that shared memory corruption was (and still is) happening. But now I don't have to restart the damn thing every hour, at least for the duration of the 30-day trial ;). However, now we've eliminated this problem, another becomes obvious. Namely that there does seem to be a small amount of memory leaking - likely due to the crashes which are still occurring (i.e. those detailed here: http://static.last.fm/phpbug/log.txt). This results in some Apache children taking up 200MB+ of RAM and lingering there, not serving any requests, until they're killed or the server is restarted. Regrettably I can't be more specific because the location in our code that the crashes happen is random (the location in PHP always appears to be zend_variables.c line 44). Since the httpd processes appear to just hang, the Apache MaxRequestsPerChild setting is useless against this. Thanks *so much* for your help so far, it is most appreciated. We seem to be ridiculously unlucky when it comes to these sorts of things... Cheers, Russ
