Subject: Alarm Reports (JSP web package)

This software may no longer be in use at SNS  but ...

on this page:


appears "Alarm Reports" a JSP Web package for viewing and analyzing the alarm configuration, which I've downloaded and works.

However it seems to "leak" RDB connections.  After running for a while the (postgresql) RDB reached it's maximum number of connections.  It appears connections to the RDB persist after the page with JSP has been closed (?) These connections eventually timeout after which the RDB will accept new connections.  Has anyone encountered this before.  Can anyone suggest an approach for fixing this? (JSP is completely new to me.)

Thanks,

John Dobbins
