Hi Imran,

It looks like some kind of socket timeout at JBoss side (or in between of c/J and JBoss, if any additional nework management exists), please explore it's config.

Also Connector/J has "socketTimeout" connection property with default 0 value, which means no timeout, please check that it was not set to lesser limit.

As for latest c/J version, I doubt it will solve this exact problem, but we always recommend to upgrade due to new bugfixes.
