Deployed app [hudson] becomes very slow after a few minutes

[effing]

Hi,
deploying the latest hudson version using Carlo's hints [https://www.jboss.org/community/docs/DOC-13233] the app becomes very slow after a few minutes. The problem is reproducible. Even clicking on the link to change the image size takes several minutes and consumes almost all cpu power (i'm on debian).

I sent Carlo the log file with 2 full thread dumps, perhaps he can provide an URL for it.

Regards,
Thomas Effing

We need to see some evidence exhibiting the problem to be of any help. Better idea to post some relevant portions of the Thread dump here than to privately email developers (unless asked). :)

Also, please note Hudson and AS versions.

I did ask Thomas to send me a full dump, but I forgot to state intent.

Normally I would have only pointed you out to the forum or support. But we also use Hudson, so I want to know about problems in advance and the original mail you sent contained only two partial traces.

This might be a better clue:

I reckon Jelly dives into some archive which VFS keeps unzipping.

What's the resource?

I guess we need to add deploy/ to cached roots as well:
vfs.xml

 <entry>
 <key>${jboss.server.home.url}deploy</key>
 <value><inject bean="VfsNamesExceptionHandler"/></value>
 </entry>
