IOZS Error: Could not create mutex for release:

[Superblue]

What causes this error? Generally it shows up in my log along with IOzs crashing when you try to scan it..

[Stardog]

It means that ioZS is already scanning in that particular release directory. Are you trying to rescan in a folder where users are uploading files to? Basically iozs detects if its running already in a particular release folder. If so, it waits for 3 secs for the other iozs process to complete. If it hasn't finished by then, you get that error.
