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: T ID KEY MODE OWNER GROUP CREATOR CGROUP CBYTES QNUM QBYTES LSPID LRPID STIME RTIME CTIME Shared Memory: T ID KEY MODE OWNER GROUP CREATOR CGROUP NATTCH SEGSZ CPID LPID ATIME DTIME CTIME m 65536 1936028777 --rw-rw-rw- setiathome setiathome setiathome setiathome 1 131224 607 34106 1:29:54 19:29:53 19:56:57 Semaphores: T ID KEY MODE OWNER GROUP CREATOR CGROUP NSEMS OTIME CTIME s 65536 1936028777 --rw-rw-rw- setiathome setiathome setiathome setiathome 1 1:29:54 19:56:57 PV ENTRY: 24, 2084665, 39395, 1837920, 5225493555 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
