Re: CURRENT: kernel crash r326347: Cannot access memory at address 0x65657246

The same problem started the last week. The problem arises when on the
CPU + I/O load  - also when I recompile ports.
I'm not completely sure but apparently I see a problem on the server (
with the same revision ) with SSDs only:
on slow HDD disk still did not hang, while the server with SSD dies
within 10-15 minutes after poudriere launching

OS: FreeBSD 12.0-CURRENT amd64 r326361
real memory  = 68719476736 (65536 MB)
CPU: Intel(R) Core(TM) i7-6700 CPU _at_ 3.40GHz (3408.17-MHz K8-class CPU)
FS: ZFS
