check why lock file was not created

Lock file mechanism seems to work fine. When I try to launch a command that is already running, I get the below error message:

The file lock is being held by a different process

Could it be that the previous instance eats up all the resources and the second instance is unable to verify the lock file status?

the lock file was not there at all
