--- Comment #1 from Jurij Kovacic <jurij.kovacic@ocpea.com> ---
Hello,
After approximately 1 month, the server (FreeBSD 11.2-RELEASE-p9 #0 r344062)
has crashed again.=20
It seems to me, the reason for the crash is most likely the same as the last
time:
Fatal trap 9: general protection fault while in kernel mode
cpuid =3D 2; apic id =3D 02
instruction pointer =3D 0x20:0xffffffff82299013
stack pointer =3D 0x28:0xfffffe0352893ad0

code segment =3D base 0x0, limit 0xfffff, type 0x1b
=3D DPL 0, pres 1, long 1, def32 0, gran 1
processor eflags =3D interrupt enabled, resume, IOPL =3D 0
current process =3D 9 (dbuf_evict_thread)
trap number =3D 9
panic: general protection fault

The "crashinfo" txt file is available at thie URL:
http://www.ocpea.com/dump/core-5.txt
original core dump files are also available if needed.
Can someone, please, take a look at this? I will be more than happy to help
with debugging, supplying additional info etc if needed.
Kind regards,
Jurij
