Hi all,

during the alfresco shutdown (deployed in tomcat 5.5.23) in the log there are thousands of errors:

Have anybody seen the same error?

Do you have other apps in tomcat? I don't think Alfresco actually uses that library!

Thanks,

Kevin

Do you have other apps in tomcat? I don't think Alfresco actually uses that library!

This usually happens after the PHP module has been installed.  I keep meaning to enter it in JIRA, but forgetting.

And yes, literally thousands of repeats (by the size of the log files I'm guessing around 10000)!

Hi,

Yeah, I've heard people mentioning something similar before although I've not seen it myself.  The issue is comming from the library that we use for the Java PHP interpreter.

We are going to be updating the Quercus jar to their lastest release so I'll check whether this continues to happen.

In the mean time raising a Jira issue will ensure this problem doesn't get missed.

Cheers,
Roy
