Re: Hung thread - Mailing list pgsql-jdbc

This question might some one has asked but did not get the proper resolution in any thread.  Henceforth posting.

I am facing the issue of the hung thread initiated from tomcat (application server tomcat 6.0) to the database (postgresql 9.0). Using JDBC driver 9.0.

From the logs of the application server found it happened some time only. Following is the thread dump taken at the time of hung thread.  Moreover, there is no query stuck at the database level.  In one of the forum i saw it might be because of the JDBC driver. Please share your thoughts on this issue. I checked there is no network level interruption.
