Hello Maxime, To answer your questions, “Looking at the screenshots, it seems that the issue is happening in the c3p0 library, not the Wrapper itself.” Ok, the trace does not show where this is being used so it must be Quartz that is using it. Did the Wrapper restart the JVM during the week ? No From: Maxime [mailto:ma...@ta...] Sent: Tuesday, January 26, 2016 12:24 AM To: wra...@li... Subject: Re: [Wrapper-user] c3p0 resource pooling 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...<mailto:su...@ta...>. Best Regards, Maxime On Tue, Jan 26, 2016 at 1:35 AM, Martin, Christopher C.
