Rig went offline

Last night my rig went offline. I found that files /hive/bin/agent and /hive/bin/wd was modified this time. And the file “agent” is corrupt (syntax errors). Is it only my local incident? What could be the couse of that?

Hi, may i know how you were able to see the Logs for that error. For the last two days i got two offline reports but do not know what was the cause.
