Unable to view Site Activities on some Site.

[Syedjunaid]

Hello everyone,

I have deployed Alfresco Community v6.0.a in a production enviornment. Our client has been facing a critical issue on some sites. The problem is that there are no activity logs on some sites. I requested them to send me "alfresco.log" file, so that I could get an idea about what might be the problem. After reviewing the logs I am unable to understand what is the error about and how it can be solved. Did some research on that error but didn't find anything.

Here are the errors occuring in alfresco logs.

Would be grateful if anyone can explain me what is this error and how can I resolve this problem.

Please use / update to a proper GA version of Alfresco 6.0 and test with that to see if your issue still applies. In general, using an early access version like 6.0.a in production is not really recommended unless you are willing to support such an installation yourself with low-level fixes or are prepared to upgrade when necessary. The proper release version for 6.0 would be 6.0.7 GA.
