VPS not doing anything..

[grey]

Hi

 It has happened a few times already in the last couple of weeks: My EA the VPS is not doing anything...
I have a dozen EA on VPS that normally opens +100 positions on a daily basis, but for some reason sometimes it stops "working".
Meaning that everything appears OK, but its just not doing anything...
No errors in journal either.

Am I  the only one suffering this?

Thanks
