We are also facing exaclty same problem while getting connections from Connection Pool. This error is happening in all Sun ONE AS versions from 7. We are not able to recreate this issue in our
test environment.
We see a
pattern for this issue,
Whenever there is good load in the server, swapping back connections to requests and pool is giving issues.
I am sure that the connection becomes stale at some point of time in pool. We are not able to find why ?
Connection validation is not working the way it should.
Any help ?
-Thx,
Ramanan.
