Thor queue has two Thors in it and if job ran on second cluster then Thor Slave log download does not work. It seems
fails. It may be that the other Thor works only because its name is an exact substring of the queue name.
An example is:
queue name is: thor20_167_dev_dev
thor clusters for this queue are: thor_20_167 and thor20_167_dev02
If job ran on dev02 then Thor Slave download fails.
