The server cannot accept a client session with the client at the indicated address due to an inability to create a new thread.
Server operation continues, but the session request fails.
The cause is probably lack of memory. Ensure that sufficient paging space is available for AIX®. You might also use SMIT to determine if the number of applications is causing a memory shortage. You might also decrease the maximum number of sessions that the server can accept with the MAXSESSIONS option in the server options file.
