Connections being rejected on a V9.8 pureScale environment
Any connections being made to the database that is on a v9.8 pureScale instance is experiencing a connection hang and instance may experience a 'hang' like situation.
If we take a few iteration of stacks (db2pd -stacks all -rep 10 5), and the stack analysis may have the following output:
0x0900000000533990 _p_nsleep + 0x10
0x0900000000038BE4 nsleep + 0xE4
0x090000000015B290 nanosleep + 0x190
0x0900000007058B60 ossSleep + 0x80
0x0900000011B6B940 sqleUCagentConnect + 0x2C4
0x0900000011F8364C RunEDU__8sqeAgentFv + 0x14C
0x0900000011F90020 sqloEDUEntry + 0x2E4
Based on this, first check we can do is to ensure DB2_
For the problem I faced the work around is to set DB2_
If the above workaround is not applicable or doesn't work, then more analysis needs to be done and DB2 Support can be engaged.
