High memory usage...
For the last week or so I have had problems with my server. During the day the memory usage have continued to rise just to finish off with crashing every night!The crashes have now been stopped - they were caused by a cron job that was going through the log files!
However, memory usage is still extremely high! The server has 512 MB of memory and usage is now 90%+. Sites on the server are based on PHP and MySQL, activity is not that high and should not amount to 90% memory usage. Something seems to be 'bleeding' memory.
How do I find out what is going wrong, i.e. what is causing it ?!
