Miner just seems to stop mining at certain points, nothing is happening, no crash, just stops mining like it's in pause mode. Checking MSI Afterburner, all clocks are dropped down like it's not mining anything and miner screen is just sitting on idle. Is this a known issue? I have 8x 1080 ti rig using this new 1.09a version. It's been paused like this for 10 minutes now, I will be restarting it in a minute.

Update: I was about to restart it but I just decided to hit backspace to see if something happened and soon as I did it kick started again? Then I got this:

[ERROR  ] 18/05/09 22:52:56 submit_upstream_work stratum_send_line failed

And then after a few more retries it kicked in and is working again.

Few more pauses have occurred, some for 2mins, some for shorter, but I don't know if it's because Suprnova is overloaded with 11k miners or what the deal is. Switching back to 1.08 overnight and switching to 1.09 in the morning when I can monitor it again.
