Can't you help much on this. I know a similar situation from a Linux box which was running out of memory, swapping heavily and to get some more memory free just killed randomly(?) processes, until we noticed something was not responding anymore. When this happened, there were entries in /var/log/messages (no clue on OS/X) which showed all the killing and I think there were also messages about memory problems.
You can either wait if someone with OS/X knowledge hopefully answers here in this thread too - or google if there is any how-tos or something to detect and analyze a memory leak on OS/X.

Ok thanks. I found this leak command and run it on some processes.

Code:
mail:~ timgolding$ ps -ax | grep http
18780  ??  Ss     0:00.62 /usr/sbin/httpd
18781  ??  S      0:00.05 /usr/sbin/httpd
18897  ??  S      0:00.00 /usr/sbin/httpd

Gives the following
Code:
mail:~ timgolding$ sudo leaks 18780
Process 18780: 17422 nodes malloced for 1818 KB
Process 18780: 8 leaks for 336 total leaked bytes.

Does that mean apache has memory leaks? If i try it with mysqld i get

Code:
mail:~ timgolding$ leaks mysqld
Process 18782: 40289 nodes malloced for 34878 KB
Process 18782: 0 leaks for 0 total leaked bytes.

---------- Post updated at 08:17 AM ---------- Previous update was at 01:25 AM ----------

I cleaned up some of my code. I think the memory leak was caused by tcpdf. Or might of been because i had too much of my program flow in one script. Either way everything seems to be working today. I made sure i revisited all the web pages i visited yesterday after the clean up and fingers crossed no memory leak. Thanks for your help zaxxon Smilie
