this system was migrated from another company, apache is configured for
4000 clients.. server worked well, now it only does 5-20mbit. i have
another server doing 130mbit with same config, except for
vm.pmap.shpgperproc=1000 on the bigger server is
vm.pmap.shpgperproc=2000 and it's a QUAD processor, same amount of ram.
i have since removed the loader.conf file and will test to see if that
has anything to do with it.
during the last crash, i had set kern.ipc.shm_use_phys=1 and it crashed
a few hours later. now i'm not sure if any of this is linked.. for all i
know, it could be a client doing something.
any suggestions would be appreciated.
thank you.
