> Your expertise on my problem will be helpful.
> Once a week, I get a DB connectivity problem with my application.
> No new DB transaction can be open. After a few minutes, the situation can
> come back as normal, if not the Geronimo server has to be restarted.
> I ask our technicians about connectivity and performance, but they found
> nothing wrong.
> I give you the stack trace in attachment with the different kind of error
> message.
> You will see that it looks like a network problem, but maybe this could also
> be due to a jdbc, timeout...?
> My pool configuration is as follow
> Pool Min Size:25
> The minimum number of connections in the pool. The default is 0.
> Pool Max Size:140
> The maximum number of connections in the pool. The default is 10.
> Blocking Timeout: 5000 (in milliseconds)
> The length of time a caller will wait for a connection. The default is
> 5000.
> Idle Timeout: 5 (in minutes)
> How long a connection can be idle before being closed. The default is
> 15.
> Any help will be appreciate.
