C3560 rebooting issue out of blue.

[hjson0001]

Hi

Many customers of mine have been using C3560 SW and yesterday, I was told that some C3560 switches was rebooted suddenly.

There was no tasks relating network or no due to power supplier. 

Sites are different case by case, though C3560 switches are rebooted.

I am wondering if there might be some bugs on OS.

Have you ever seen this rebooting issue before? Now, we are checking the other site's switches building in similar period.

Thanks regards.

OS version is below.

Hi @hjson0001 ,

Effectively, the symptoms seem to be from an IOS bug.

I recommend you update the IOS:
