Problem IC95355
|
Status: Closed |
DB2TCPCM EDU NEED TO HANDLE SETSOCKOPT() FAILURES MORE GRACEFULLY |
| product: |
DB2 FOR LUW / DB2FORLUW / A50 - DB2 |
| Problem description: |
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:
