[BUG] Cisco Nexus C3548P-10GX auto reboot randomly

[NguyenBinh1008]

Hi everyone,

I have couple of Cisco Nexus C3548P-10GX config running VPC with it.

I have an issue that: the couple of switch randomly reboot unexpectedly with the reason i saw the the `show system reset-reason` command is that:

•  show system reset-reason
  ----- reset reason for module 1 (from Supervisor in slot 1) ---
  1) At 125844 usecs after Mon Aug 12 19:49:07 2019
  Reason: Reset Requested due to Fatal System Error
  Service: sysmgr failed to re-register with heartbeat klm
  Version: 9.2(2)
  2) At 12819 usecs after Sun Jul 28 16:42:09 2019
  Reason: Reset Requested due to Fatal System Error
  Service: sysmgr failed to re-register with heartbeat klm
  Version: 9.2(2)

My switch system information below:

• Software
  BIOS: version 5.0.0
  NXOS: version 9.2(2)
• Hardware
  cisco Nexus3500 C3548P-10GX Chassis
  Intel(R) Pentium(R) CPU @ 2.00GHz with 4030544 kB of memory.
  Processor Board ID FOC230156CG

I search for bug on cisco page, but no report about this issue with NXOS 9.2(2).

Anyone have met this issue? And is there any solution or patch fix for this bug?

Thanks So much!

It seems to be the same situation as this bug with the 5.0 release NX-OS : https://bst.cloudapps.cisco.com/bugsearch/bug/CSCup90920/?rfs=iqvred
