suggestion: a script to take a snapshot of the /proc filesystem so you can find what's growing
take a look at dir /proc and cat /proc/<ID>/status or cat /proc/<ID>/maps
Thanks for that. We've been looking at status but we need to wade through all the output. maps is a new idea and we'll have a look. Doubtless you will hear more as and when we get closer to the root of this problem.
