Re: [Wrapper-user] c3p0 resource pooling

[Maxime <ma...@ta...>]

Martin,

Thank you for the information.
Looking at the screenshots, it seems that the issue is happening in the
c3p0 library, not the Wrapper itself.
Did the Wrapper restart the JVM during the week ? You may find more
information about the state of your Java application in the log files of
the Wrapper.
If you want to investigate this matter further, please send the log files
to su...@ta....

Best Regards,

Maxime
