Solaris Common Messages and Troubleshooting Guide

Action

Simply waiting often gives the system time to free resources. However if this message occurs often on a system, reconfigure the kernel and allow more processes. To increase the size of the process table in Solaris 2, increase the value of maxusers in the /etc/system file. The default maxusers value is the amount of main memory in MB, minus 2.

If one user is not allowed to create any more processes, that user has probably exceeded the memory size limit; see the limit(1) man page for details.
