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 Solaris. You may also use ps -ef 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.
