We are getting these errors on a particular page. Looking at the code there is nothing wrong that we can see other than the fact that it is manipulating a large amount of data.

 

Any ideas on what we can do to eliminate these issues.

What is the memory state of your server when this happens?

Looks like you may just have some operation on the page that is using up all the server's memory, and then dying on you.

Dale,

something on your page seems to go crazy and suck all the remaining
VM memory.

Cheers
Kai

Yeah,

I've been told that the code is ok, but I think I'll need to look through it
myself.

First thing that comes to mind is Sessions.

If you are placing a lot of data in the session scope, your server can
be brought down by all kinds of traffic especially spiders.

And then there's excessive caching. If you are caching on a per-user
basis or not caching effectively (e.g. storage bugs, whitespace) you can
get this.

Depends on your application. Perhaps it is loading some huge data
structure into memory but it would have to be excessively huge to bring
down the server.

My two cents

how much memory do you have allocated to the cf jvm?
