Good morning,

I’m having an issue with my server that’s driving me crazy.

The problem is that the server randomly freezes — it becomes completely unresponsive: no web access, no SSH, and it doesn’t even respond to ping. The freeze can occur after a few hours or sometimes after several days, with no clear pattern.

It’s a DIY build based on a CWWK N100 motherboard, Crucial DDR5 memory, four 12TB HDDs, and an SSD used for pool.

The main issue is that when I enable syslog, the system freezes before any relevant entries are recorded, so I get no logs. I’m not entirely sure how to configure logging to an external location in order to capture what’s happening before the crash.

Any advice would be greatly appreciated.

Best regards,

Thank you.

This almost certainly means a hardware issue. Logging to an external source is unlikely to help if you have set the syslog server to log to the flash as that is more likely to catch something (if there is anything to catch) than a network resource.

You are likely to get more informed feedback if you attach your system's diagnostics zip file to your next post in this thread.

It is always a good idea to do this to allow us to see the current state of your system and so we can see logs.

Good morning,

Attached is the diagnostic report.

Based on my testing, I also suspect a hardware issue. I have tested multiple RAM modules, an alternative power supply, and several USB drives, all producing the same failure. My current hypothesis is that the root cause may be either the motherboard or the cache SSD, although I am unsure if the SSD could be responsible for the behavior observed.

thanks!

Ideas?

if you have multiple sticks try using the server with just one, if the same try with a different one, that will basically rule out bad RAM.

I’ve tried with three USB flash drives and three RAM modules (Integral, Crucial, and Corsair) with the same results.

Board, CPU or PSU would be the next suspects.

I have a DXP4800 and have the same problem as you. The memory test passed without any problem. Now I downgrade the system to 7.0.1 and test it again.
