robot.cfg getting blank/robot inactive

[Sid]

Hi Team,
has anyone experienced issues with robot cfg going blank . We have been seeing this issue very frequently.
We already have required ports opened, AV rules for excluding nimsoft dir in place.

There have been some prior threads on this and Garin had provided some good insight into this. From a support perspective it is easy to come up with a virus scanner as being a most likely cause. Beyond that we are looking at two things accessing robot.cfg at the same time, controller (which does both controller.cfg and robot.cfg) and that something else. controller does its thing and then that other thing whatever it is virus scanner, someone with the config GUI, or whatever, prevents the controller's operation from completing and wack. 

Some statistical work might be most beneficial here, checking robot versions, configurations, OS, timing on when and frequency.

Any AV tool that undoes changes to files or interrupts the write of new files is suspect here. CarbonBlack is a big offender in this arena from recent experience.

Also make sure that the ACLs assigned to the files and directories don't get confused or messed up. If not careful when mucking with ACLs you can create a scenario where you can delete a file but not create a new one. When the controller shuts down it rewrites the robot.cfg file and that involves removing the existing file and creating a new.

Make sure that there's enough disk space, the controller doesn't care when the disk is full that it can't write the new file. It will ignore that and since it has already deleted the original you are done. 

And finally make sure that you don't have anything going on at the OS/hardware level that might be causing this - look to drive write caching, filesystem sync, etc. where the controller might be operating correctly but do to the OS/hardware those changes the controller is making never get to physical disk.

In older robot versions there was a possible problem when audit was active
