Also I'm registering some problems with DSTM's ZM miner 0.5.8 while reconnecting to the pool (it happened just twice for 14 days - nothing terrible):
Computer si WINDOWS 10 ENTERPRISE LTSB 2016 64-BIT, MSI GTX 1080 Ti, 100 Mbps wired network, uptime around 4 days.
On other computers I'm running 0.5.7 and it never happened yet.
Thx for reporting.
I've a test case for this, something like reconnecting every 10sec/randomly for a couple hours - it works on my systems fine.
Be aware that zm stops all GPUs during connection loss to save energy - if your system is unstable/overclocked it's likely to crash during stop/start cycles.
I'll let the test case run again to make sure there are no issues.
