Hi,
( In case anyone is still subscribed to cfaussie )
I have recently moved some code from cf6 to cf9 enterprise and a particular
process consumes all of the resources and hangs the CF server. The exact same
code on CF9 standard works okay ( although different windows server version ).
The code is processing HL7 messages ( health messaging, admission, discharge
messages etc ) and basically it works in a continuous cfloop, selecting the top
1 message from the database, and calls a bunch of extra pages to process the
messages.
My errors look like the following, from the log file:
10/12 14:58:20 error ROOT CAUSE:
java.lang.OutOfMemoryError: GC overhead limit exceeded

I have moved the process back to my old server ( cf6 ), but the server admin
team would prefer that the server is removed sooner rather than later.
I am contemplating putting another website on the cf9 server and running it
from there.
There are few online forums with posts regarding similar problems, which mostly
refer to var scoping variables in functions, or are looking at object creation.
I am seeking specific advice regarding what to do in this instance. Any gotcha,
quick fixes, things to double check?
