JRun problem in ColdFusion Dev edition…Help Please!
Hello all,
Well then, I spent a few hours today trying to troubleshoot a little problem without any luck. I noticed that my machine was running crazy slow and when I looked at my services, I noticed that CF was running at 600MB by itself. This has never happened to me before, so I went poking around trying to find the culprit and I still don’t know what’s up. Has anyone had an issue with CF running on Vista or any OS where JRun peaks at 500MB or more? I haven’t changed any settings since the first install, soeither CF doesn’t like my machine or there is something sitting on my machine that is in conflict. Any help is much appreciated.

Keyword: disk access, deadlock, infinite recursions…
Advice: Avoid all of them.
Tip: Mainly its the code.

I don’t think it is the code, it happens when I start the service for the first time. Thanks for the reply though.

Have you taken and reviewed thread dumps? Enabled and reviewed GC logging? Maybe you could also just post your jvm.args here too?

Awesome! Thanks for the links, I started playing around with the CF startup on two machines and I noticed that if I have the RAM available CF eats it up, but if I don’t it scales down. I thought that was weird since the server always ran at 64-90MB on my machine. I will check out the links and will post any solutions that I find. Thanks again.

Lu, you haven’t said: is this cf8? If so, have you tried to use the server monitor? Indeed, beside it possibly helping solve things by showing what’s running, it could also be a cause if you’ve left the “start memory tracking enabled”. If so, then even with the monitor closed it can still be stealing resources. Maybe not memory, but worth checking.

@Charlie
Nope, I haven’t used the server monitor at all, but I will try it out. Right now it’s running at 98MB, maybe it’s an issue at startup and when it’s been running for a while it throttles down.
