ethOS 1.1.2 does not start startum proxy or ethminer after the update

I have rig with 6xRX480 cards and I was running ethOS 1.1.1 without any problems, today I upgraded rig to 1.1.2 and minestart command does not work
output is
/root # minestart

miner started: finishing boot process
File /tmp/minercmd is empty so probably php script located in /opt/ethos/lib/minerprocess.php has some kind of bug.
Also stratum proxy didn't start and it works when it's started manually by command
python /opt/eth-proxy/eth-proxy.py

Any help here is more than welcomed.
