Right, I've left it going for a couple weeks and only 4 procs end up with cpu time.. Not only that I've pounded the server and tested with external scripts, I've never seen more than 4 being run at once.. All the hints point to 4 as being the magic number. -----Original Message----- From: Greger V.

At any given time you may have processes without CPU load, but over time the processes should have some CPU time. Have you run serctl ps? AFAIK, the standard number of processes for each protocol (udp/tcp) is 8 unless you specify children=x. If a ser process blocks due to problems with mysql or a radius failover situation, you may get a problem where all processes blocks. g-) Matt Schulte wrote:
