ColdFusion VM Abort

Just recently I got to see this from one of my support customers:

It showed up in the cfserver.log and I was wondering what it could be about. A quick chat with Tom Jordahl from the CF team here at CFUNITED pointed me in the right direction. The machine seemed to ran out of memory for the PermGen in the JVM (permanent generation). A typical issue related with that in CF is if you set your CF server to an extremly high value for “Cached Templates”. Doing this, a lot of permanent JVM memory is reserved for the objects CF is creating during compilation and runtime of templates.

In this particular case, the setting was 10000. We decreased it now to a more reasonable value and monitor how it works for them. Another option is to increase the JVM memory area for the PermGen so that you don’t run out of memory with it.
