Re: Sudden cpu spike: msg#00106 webobjects-deploy

This is still an issue for us.

We have a site with the following:
OS 10.5.7
2.8 Ghz Quad-Core Intel Xeon
WebObjects 5.4.3
Java 1.5.0_19
Apache2.2 (We are using the Apache adaptor from Apple right now, and not the Wonder version)

There is one instance of our app.
There are about 7 sessions running.
Each session has a separate connection to the database.

Within about 5 hours or so, all 4 processors run at close to 100%, until eventually the app stops responding.
We have a few sites that have this problem, and the only thing i can see in common is running WO5.4.x on Leopard.

I did manage to get the jstack output when this machine's cpu usage was close to capacity.
Below is the jstack output.

Does anything jump out as obviously wrong to anybody?

admin$ sudo jstack 17494

Hi Doug,

Still in need of help-

I took your advice and made a build specifically for this site using java 1.5 and the latest xcode and wo.
I am still having this problem.
We have one instance of our application that is causing each processor to spike to over 90 percent of its cpu capacity.
When this happens, one random user will get the 'instance not available'.

Have you gotten a thread dump from such a run away instance?
http://www.gvcsitemaker.com/gvc.webobjects/ faq&mode=single&recordID=41413

Is that one specific instance, or just randomly one of them? If one specific, what is different about it?

This only happens when someone upgrades to WO 5.4.2 or 5.4.3.
Tiger machines running WO 5.3.x have no problems.

Are the machines upgraded to WO 5.4 running a copy of the app compiled against the same version of WO?

These are intel machines running OS 10.5.x.

Does anyone know of any changes made in WO 5.4.x (or OS 10.5.x) that could cause this?

Not off hand.

No, they were built using Xcode and WO 5.3.3.

This is a really bad idea ... I would never deploy on a version that's different than development. It's just asking for problems. While it MAY work, you're just playing roulette with your app. Either 1) replace 5.4 with 5.3 on that server, 2) rebuild your app with WO 5.3 embedded, or 3) Setup a proper 5.4.2 build and development environment and rebuild and test your app in 5.4.2.
