'512' with no minimum specified. I don't recall ever changing this so presume
that this is the default MM setting. What would you recommend altering this
value to?
A quick check on the machine now reveals that the memory state is as follows:
Mem: 1285500K av, 950896K used, 334604K free, 56K shrd, 134004K buff
Swap: 1020088K av, 0K used, 1020088K free 529076K cached
There are then multiple instances of:
PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND
1069 nobody 25 5 241M 241M 21708 S N 0.0 19.2 0:00 cfusion
Sorry for appearing a bit stupid here but is the '241M' size above governed by
the JVM Heap Size? If more RAM was available, this would just grow to a max of
512?
What governs the number of instances of 'cfusion'? I can see that the bulk
have no 'TIME' value and '0.0' %CPU. Should these not be timing-out in some
way sooner and then clearing up the available memory?
Thanks,
Matt.

The JVM allocates memory for the heap which may or may not contain any actual
objects. When there is contention for space in the heap - the heap grows until
the max heap size is reached.
