Does anyone have this problem: periodically hashrate drops by 50-60% and doesn't recover until reboot.

Rig with 13 Nvidia 1060 cards under Ubuntu running Claymore 10.6. It can run days without problems at steady 315Mh/s, but always ends the same way: hashrate drops to 120-140Mh/s, web api not responsive and I can't access machine via Teamviewer - need to go and reboot it.

Here's screenshot from Ethermine and part of log file when this happens:
