DB2 FOR LUW / DB2FORLUW / A50 - DB2

If a new incoming TCP/IP connection is accepted by the db2tcpcm 
thread, but this connection is disconnected immediatly by the 
remote client, then subsequent setsockopt() calls may fail with 
errno 22 (EINVAL) on AIX. This problem has been observed on AIX 
only so far, but could potentially happen on any platform. 
 
This error is considered critical and error handling may cause 
the db2tcpcm edu to terminate. After this problem any remote 
connections to DB2 will not be possible anymore. The DB2 server 
may appear to hang for new connection attempts. 
 
A typical db2diag.log would show:
