Description :When there is an authentication error to the Manager SAP, the thread used for authentication is not released, which consumes a file descriptor, and causes the Manager for SAP not stopping when calling uxend fnc fnc=SAP or via UVC.

Environment

OS: All
Related configuration item(s): 6.3.41

Cause

Cause type:
Defect
Root Cause: When applications other than SAP were attempting to connect to Dollar Universe's Manager for SAP via its TCP port, they would create a socket connection to the Manager for SAP. Since the communication to the Manager was not from SAP, the Manager did not handle it correctly and did not liberate the socket connection and therefore a thread remained in use for this socket connection. Eventually, the system would run of threads due to the amount of unclosed non-SAP socket connections. One example of an application that could be causing such a connection issue is a TCP monitoring solution that verifies if the Manager for SAP's TCP port is still available (ex: Compuware).

Resolution

Dollar Universe's Manager for SAP version 6.4.41 and above now requires authentication for any connection over its TCP port and will close any unauthorized socket connections.

Fix Status: Released
