VM segfaulting in (seemingly) random moments

[maniel]

Hello
I'm using headless virtualbox setup on a FX-8150 (8 cores) machine with 16GB of RAM. Besides the virtualbox there's docker deployment of graylog stack (graylog, elasticsearch, mongodb) which generates fairly heavy I/O load. The underlying file system is BTRFS. The VM segfaults from time to time, only thing i'm getting is the following line in `dmesg` output:

Code: Select all

EMT-0[3599]: segfault at 7f4264096000 ip 00007f427f0b14d8 sp 00007f4279245ab8 error 4 in libc-2.23.so[7f427ef5b000+1c0000]

The VM has 4GB of RAM and 4 cores assigned. Of course I disabled CoW BTRFS functionality for VM images. Them machine is running Centos 7.5.1804 with XFS filesystem (it's Eset's ESMC OVA)
The problem occurred on both Virtualbox 5 and 6
Is there anything i can do about it? also is there any watchdog kinda software i could use to make VM start automatically after a crash?
