I never saw mlock(2) fail in 6.2 but with 7.0 I sometimes
get mlock(2) failed: Resource temporarily unavailable.
I commented out a ton of drivers in the kernel config file,
which I didn't do in 6.2, so the 7.0 kernel should be using less
memory, unless something still in there gained a lot of bloat.
dmesg says:
usable memory = 2139107328 (2040 MB)
avail memory = 2064769024 (1969 MB)
pstat -s says:
Device 1M-blocks Used Avail Capacity
/dev/ad6s10 4482 0 4482 0%
so there should be far more than enough memory.
systat -vmstat says:
Mem:KB REAL VIRTUAL VN PAGER SWAP PAGER

All 255092 8900 4688532 19072 pages
and mlock is failing.
What changed and how do I fix it?
