Morning ...
I have a server with the following specs from DMESG:

Which crashes on me at around 2am in the morning (either after 24
or 48hrs of uptime, depending on my luck) with the following error:
| panic: vm_map_entry_create: kernel resources exhausted
| mp_lock = 01000001; cpuid = 1; lapic.id = 01000000
| boot() called on cpu#1
Attached at the bottom of this is my current kernel config ...
last night, I ran top on the system and cut-n-paste the results from when
it hung, which look like:
last pid: 84988; load averages: 19.82, 57.35, 44.426 up 0+23:33:12 02:05:00
5021 processes:16 running, 5005 sleeping
CPU states: 8.7% user, 0.0% nice, 24.3% system, 2.2% interrupt, 64.7% idle
Mem: 2320M Active, 211M Inact, 390M Wired, 92M Cache, 199M Buf, 4348K Free
Swap: 3072M Total, 1048M Used, 2024M Free, 34% Inuse, 448K Out
So, I have plenty of swapspace left, lots of idle CPU and a whole whack of
processes ...
Someone suggested setting KVA_PAGES higher then the default for
this, but, as this is a production server, and its not something I've ever
played with, I'd like to know what the ramifications are ...
The server has 3Gig of RAM now ... according to opt_global.h,
KVA_PAGES is set to 256 (1G) right now ... but if its 1G by default, how
does a system withi <1G of RAM in it "work"? Or does this limit something
else altogether? I'm not finding any good 'reading material' on this so
far, but from waht I found through a search, it seems that its recommended
to be set to 768(3G) vs 256(1G)?
Thanks for any help in advance ..
