MAXPROCESSCNT is a system parameter that sets the number of process entry slots allocated at bootstrap time. One slot is required for each concurrent process on the system. Each slot requires 6 bytes of permanently resident memory.
The default value is normally configured to allow you to create the desired number of processes. If the following message appears, you need to increase the value of MAXPROCESSCNT:
%SYSTEM-F-NOSLOT, No PCB to create process
On Alpha and Integrity servers beginning with Version 8.1, the default value is 32,767.
MAXPROCESSCNT has the AUTOGEN, FEEDBACK, GEN, and MAJOR attributes.
