Example: (the location, ipaddr and port will contain valid values, the message below is a sample only) DSNL511I DSNLIENO TCP/IP CONVERSATION FAILED TO LOCATION .... Resolution Reproduced the issue with Connect for ODBC 5.2 and 5.3 Defect DD00037949 was filed and the issue is no longer reproducible using builds of 5.2 and 5.3 dated after January This leads to a situation where a DBAT may close a socket that has already been closed or, worse, has since been assigned to another (requester or server related) thread. This blocks all subsequent connection requests to the DB2 server and effectively causes the DB2 TCP/IP Listener task to be non-functional. http://gbnetvideo.net/return-code/socket-recv-return-code-1127-reason-code-00000000.html

Please tell us how we can make this article more useful. This can be caused by clients that are no longer responsive (or no longer connected to the network). This problem occurs because the DB2 TCP/IP Listener task is waiting to accept the connection request from the client system, but the connection has already been reset by the client system.
