"sokva" again



Hi,

I hope that someone can help me. httpd processes are again having a state of sokva. I can't say for sure, but it seemed to make the problem worse when I added 2 more IP's to ifconfig and then added 3 ssl sites to my apache conf. The system has 3 network cards and 5 IPs now.


I have this in my kernel config:
maxusers        64
options         ALTIVEC         # Include AltiVec support
options         MAXFILES=32768
options         NMBCLUSTERS=32768
options         DFLDSIZ=402653184

I really can't understand this. If I build a kernel with: options SOSEND_NO_LOAN then I after a few days the system stops responding. What is really weird is that it intermittently responds to pings.

I have been thinking about building a kernel with options KMEMSTATS. Would this mean a performance hit?


I have this in my sysctl.conf:

vfs.nfs.iothreads=4
kern.no_sa_support=1
kern.somaxkva=75497472
kern.maxfiles=65536

All I can think is the kernel is running out of resources somewhere. Are there things that I could change in my apache config that would help?
