Message EDC8102I OPERATION WOULD BLOCK is seen in the stderr file. Is this an error situation.
It is only an informational message, and will be seen often in STDERR logs for CA LDAP SERVER for z/OS.
The reason that this message is logged can be explained by the way TCP/IP sockets work, operating in either blocking or non-blocking mode. CA LDAP uses the non-blocking mode to improve performance. This informational message is produced when there is no data in the TCP/IP stack's input buffer. No action is required. Read operations automatically continue when the next data packet appears in the input buffer.
