VMware ESXi kernel panic

[nakrul]

Hello,

while copying data on a virtual machine with a Windows os from one hdd to another, the server started the configured automatic backup with veeam and ended in a kernel panic. Can you help me with the problem.

Thanks,

Steven

Hi  Steven,

The copy process and the Veeam Backup are completed successfully when run separately?

Can you reproduce the error?

I can imagine that backup fails when copying an amount of data during the snapshotting proces, but I am not sure why that would cause a PSOD.

Regards,

Bart

‌Hi Bart,

when run separately the copy process and the Veeam backup work like a charm. I will try to reproduce the PSOD on friday afternoon, I have scheduled a server maintenance then.

Hi,

thanks for the hint to the knowledge base article. I have a single esxi host with vmware vsphere essentials. I have no distributed virtual switches or port groups defined that could cause the problem.

Hi,

it seems very simmilar to the following backtrace:

(see the lines starting from <YYYY-MM_DD><Time> cpu26:9842)@BlueScreen: PANIC bora/vmkernel/main/dlmalloc.c:4827 - Usage error in dlmalloc:)

VMware KB: VMware ESXi 5.1.x host fails with a purple diagnostic screen and reports the error: PANIC...

Cause

This issue occurs if there is an issue with CPU hardware. 

Resolution

To resolve this issue, contact your hardware vendor for assistance. Also, consider a BIOS upgrade, if available.

Hi,

I upgraded the to the latest bios version last friday. During the next scheduled maintenance I will try to reproduce the kernel panic.
