Hello,

if you like help you have to provide more information like.

[blueice]

hello
you have find any solution?

 

[jcmluquez]

Hi, having the same problem here!
In my case, I have a VM running a PfSense and I think this "blocking state" is making PFsense interfaces disabled.
Please help!
Thanks

I have the same problem with Freepbx VM! Every 2 days vm freeze
