Those are very different crashes.

I'd guess that the second crash is a result of the first one since it crashed before it finished booting, just after mounting the filesystem.

Is this the first time that has happened?

[ojosaghae]

@stephenw10 Yes it is.
This was in relation to this issue. I decided to just do a clean install, so I downloaded the image from Netgate and set up a new machine, then restored the backup I did from the old machine. It worked cleanly without any errors. And then after some days, this came up.

[stephenw10]

Any idea what might have been happening when it hit that? Any unusual traffic?

[ojosaghae]

@stephenw10 There was something I noticed.
I suddenly noticed snort was throwing up some alerts - Potentially Bad Traffic and Generic Protocol Command Decode. I uploaded a couple of sample screenshots..

[stephenw10]

I ran it past one of our developers who said something unusual must have happened to reach that because it shouldn't be possible. That was just his first comment, hopefully there will be more when he has time to review it properly.

Steve

[ojosaghae]

@stephenw10 Thank you so much.
I look forward to the feedback from you (and your developer team)

[stephenw10]

Ok that second crash looks like it could be a hardware issue which means the first crash could also be. If you haven't seen this before or since that might also indicate hardware. Are you able to run a memtest on that hardware?

[ojosaghae]

@stephenw10 Hi and apologies for the delay in replying.
I ran memtest on the server - more than once. I ran the basic, and then the advanced (which ran for hours). There was no error at all.

Any update concerning the first crash please ?

[stephenw10]

No updates I'm afraid. It still looks like harwdare, though clearly not RAM from that test.
