i386: vm.pmap kernel local race condition
...sses.
Lesser number of ntlm_auth sometimes results in squid crash
as it sometimes has several hundreds requests per second to authorize
and is intolerant to exhaustion of free ntlm_auth.
"squid -k rotatelog" at midnight results in crash:
Feb 14 00:03:00 irl savecore: reboot after panic: get_pv_entry: increase vm.pmap.shpgperproc
Feb 14 00:03:00 irl savecore: writing core to vmcore.1
Btw, I have coredump.
vm.pmap.shpgperproc has default value (200) here, as well as m.v_free_min,
vm.v_free_reserved, and vm.v_free_target and KVA_PAGES.
These crashes are pretty regular
