Subject AW: [Trinidad] Causing Too many open files error?
Date Thu, 21 Jun 2007 07:42:37 GMT
The problem is reproducable. After restarting tomcat and some requests to my application the
jar file will again be opened multiple times. Every (initial?) request to a page increases
the number. Eventually after some time the files are garbage collected.

I saw this as well using Oracle JDeveloper so I agree that I don't think this is a Tomcat
issue.  I'm not sure what might be causing this though because I shut down my webserver and
restarted it and everything has been working fine since. 

What happens when you restart tomcat?

we are developing a quite simple application based on MyFaces, Trinidad and Facelets. After
deploying this application to a Tomcat 5.5.23 and using the application for a while we are
facing connection errors in Tomcat caused by too many open files.

Checking the running Tomcat process with lsof (list open files) we discovered, that  <application>/WEB-INF/lib/trinidad-
impl-1.0.1-incubating-SNAPSHOT.jar was open for about 300 times. The number rises with every
request. At some time eventually a garbage collection closes all these files.

I don't think this is a Tomcat error, because this jar is the only jar file opened so many
times. Perhaps some Trinidad code fails to close a file? Is this a known issue? 

Many thanks in advance.
