Enterprise Integration Forum : IBM Lotus Connector for SAP crashing our server

Hi.

We have some applications connecting to SAP R/3 systems. It crashes the server after days of stably running agents within these applications. Please note that the case is not application specific, or the crash occurs only when specific agent is run. It occurs, to whichever agent it picked that uses the connector to connect to SAP.

After crashing the server, admin will restart the server and again, after days of stably running those agents, the server would crash again. and the story goes on... and on.

This has been happening for months now.

Thanks for your help.

Here are some of the NSD logs captured:
