Stream Closed errors in defaultTrace

I have been evaluating our logs/trace files looking for potential problems with our applications (not because I don't have anything better to do We have an error in the defaultTrace file that occurs over and over again. The error is as follows:

#1.5#00096B6B4AFD0015000015290020504C0004382920CC469B#1187649201915#com.sap.engine.services.servlets_jsp.server.HttpHandlerImpl#pcbp.com/PCBPa#com.sap.engine.services.servlets_jsp.server.HttpHandlerImpl#J2EE_GUEST#0####5b7bc5a04f6d11dca0de00096b6b4afd#SAPEngine_Application_Thread[impl:3]_22##0#0#Error#1#/System/Server/WebRequests#Plain###Processing HTTP request to servlet [jsp] finished with error.

I'm curious as to what this error is. The users are not complaining about something not working or anything like that, but the message seems like something is not correct. These errors are being triggered by custom developed java apps running on NW04 SP14 installation. Does anyone know how I can dissect this message and troubleshoot where/what might be causing the problem?

thanks
