Jira login problem

Question

Hello,

We have Jira 4.4 installed and a colleague of mine tried to connect it with confluence (via O'auth / Application links). It didn't worked out so we've decided to use the internal DB of Jira (temp solution). But until then, every 3-4 days, we get an error when trying to log on Jira :

---

Oops - an error has occurred
System error

Cause:
com.atlassian.crowd.embedded.ofbiz.db.DataAccessException: org.ofbiz.core.entity.GenericDataSourceException: Generic Entity Exception occurred in deleteByAnd (SQL Exception while executing the following:DELETE FROM cwd_user_attributes WHERE user_id=? AND attribute_name=? (no more data to read in the socket)

Track

AND attribute_name=? (no more data to read in the socket)

Each time we have to re-start the Tomcat server and the error disappears for ~4 days. We're kind of stuck and are looking for some structural solution. Could anyone of you give us some help ?

Thanks in advance.

I agree with Azwandi, please check if someone restarted the database server shortly before the problems start

There could be more explanatory error message in the log, but for a start I'd suggest looking at the database connection persistence, as discussed in http://confluence.atlassian.com/display/JIRA/Surviving+Connection+Closures
