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, the session request fails.
The most likely cause is lack of memory. Ensure that sufficient paging space is available for AIX®. You may also use SMIT to determine if the number of applications is causing a memory shortage. You may also decrease the maximum number of sessions that the server can accept with the MAXSESSIONS option in the server options file.
