I've run JIRA under JBoss with at last count 2+ weeks of uptime.

Just recently switched to Tomcat on the above platform, and over the weekend, something must have happened to the db connections?

Anything involving more than a read of the database (meaning, updating or deleting) now fails with the following generic error:

Exception: org.ofbiz.core.entity.GenericDataSourceException: SQL Exception while executing the following: SELECT ID, pname, URL, LEAD, DESCRIPTION, pkey, pcounter FROM project WHERE ID=? (Communication link failure: java.io.IOException)

Each error trace is slightly different. For example, sometimes there will be "ERROR [some webwork action]" in at the beginning of the trace. Other times it's absent, and you have to look inside the stack to see that you were trying to do com.atlassian.jira.action.issue.IssueCreate.doExecute()

Restarting Tomcat seems to have solved the problems.

Anyone else getting these connection troubles on Tomcat ?
