Hi,
I just got this on one of our machines.... It talks about Apache
being the issue, but when I run the "ipcs -a ; sysctl vm.zone | grep PV"
I get :
odin# ipcs -a ; sysctl vm.zone | grep PV
Message Queues:

This is a server thats running a stock SMP kernel, has 4G of memory,
104 total processes, of which 4 are setiathome, and gets maybe 50 hits A DAY.
I saw where you could sysctl a fix, but it didn't seem to mention
a guideline for the setting.
Where should I go, or can I just let it go for now?
Thanks, Tuc
