SAPdb deadlock?

[Gonzalo Casas]

Hi,     Im running sap 7.4.3.17 on a W2k server, the only access to the database is through a JSP webapp with sap jdbc driver (7.4.3.17) .... there's very few users connected.... because the webapp is on beta...today, there was only ONE user connected, and the SAPdb service became soo unstable, and resource-consuming that the server was almost unmanageable... i mean, i opened a DOS window, and the chars appared on the screen with delay!!! i had to stop and restart and it all came back to normal... but, what can i do to trace to cause of the problem? any logfile/trace/any ideas on how to know what happened today?   thanks, gonzalo
