Re: apache hanging whole system

[Igor Cicimov <icicimov@xxxxxxxxx>]

Peter...apart from the one mentioned above there are bunch of tools you can use to monitor and analyze your server like webalizer, awstats etc. From what you have given us above I would expect that PHP is the culprit in this situation ... except if your application has a database back end in which case that might be the problem too (like long running db queries, not released connections etc...things that can easily consume apache resources). Without the config file we can't say what else might be wrong, it might be KeepAlive and/or Timeout settings or something similar ...
