Hello,

Having issues with my server.. Server has been stable for quite awhile (its all mostly new hardware within the year) then all of a sudden I started getting random, daily reboots, usually every 24hrs. Now today it has been happening almost every 20 minutes.. Its driving me crazy.. Usually when I run stable for awhile then start seeing reboots I replace the USB drive. This has already been done and i'm still having the same issues. I'm also already set on IPVLAN

 

v 6.12.6

 

Here are the things ive done

 

Checked File System

Installed brand new USB thumb drive

Ram Memtest
Double Checked IPVLAN

Went through the logs myself the best I could. I do some suspicious things maybe related to the NICs but I am not sure.

This is all 10gb SFP+ multiple 10gb NICs

Again, this current configuration has run just fine. So i am not sure what has all of a sudden started happening.

 

Attached is the diagnostic logs.. Looking for any direction Thank you!

The syslog in the diagnostics is the RAM version that starts afresh every time the system is booted.  You should enable the syslog server (probably with the option to Mirror to Flash set) to get a syslog that survives a reboot so we can see what leads up to a crash.  If using the mirror option the syslog file is stored in the 'logs' folder on the flash drive.

I do have syslog enabled. And it is copying the file to disk. I figured if that was set running diagnostics would pull that file. But good to know it doesn’t. How would you like me to provide the syslog file from the one that is saved? Is there a specific method? I do not have the mirror to flash option enabled. Just a local syslog directory that the file is stored. Will that suffice?

You just need to post the syslog from wherever it's being saved to.

Ok, i cleared the log, will wait for a reboot so we don't have a lot of old information. So far server has been up for 5 hours.. I have Zabbix monitoring everything so ill get alerted right away when the server restarts. Will post the time it happens and provide the syslog along with it.. appreciate the help.

I got an alert around 1:12am that the server had an unlcean shutdown.. Looks like we are back to the "within 24hrs" rebooting schedule. That is usually the normal. When i made this post it was rebooting every 20m or less non stop..

Please see attached syslog that was saved to the syslog server.. Thanks!

There are multiple call traces related to the NIC, also if the server is rebooting by itself, vs. crashing or hanging, that usually always suggests a hardware problem.

the server has 2  dual port 10gb NICs as it was used at one point as an iscsi datastore for ESXi into a Zfs pool basically had its own iscsi network isolated for that purpose. It ran like that without any issues and worked great. 

 

I believe the server is just rebooting. Not hanging or technically crashing. Can you tell which NIC it may be? Could a bad DAC cable also cause this?

Enable the syslog server and post that after a reboot, it will show if there was a shutdown event.

Thanks. My bonded interface. Will troubleshoot from there. 

I’m curious, is there a known bug with LACP in 12.6? It seems like since disabling that my server is stable again. I’ve never had issues prior with LACP. 

Not that I know of.
