ERROR: Unable to retrieve QOS Snapshot

[InsanityDude76]

good afternoon,

I was setting up QOS on our OmniSwitch 6900

I had to remove a config as I fat fingered a name with

no policy network group

but I noticed it was still in the config when I did show configuration snapshot

after trying to remove it a couple more times I started getting this error when trying to view a snapshot

show configuration snapshot
Please wait...
ERROR: Unable to retrieve QOS snapshot.

I'd like to avoid just rebooting if possible since its a prod switch but if reboot is the only fix ill schedule time to do it

for the first: maybe the missing "qos apply" was the reason. If you change policies you need the apply to activate the new config.
I assume you can't see anything with any "show configuration snapshot" (qos or stp or ip....).
I have seen this behavior some times (but long time ago). The onliest way to get the wished output was the reboot.
Maybe you can use the reboot for an update to a newer release where this issue is fixed.
