affected platforms are HP and Linux. If you encounter this
problem, the following db2diag.log messages will appear, and the
instance will go down.
The key message to watch out for is the errno at the probe 15 of
sqeDomainSocketPair::WriteConn. If the errno is 0xB (11), then
you have encountered this problem.
