Failed to check the license

Recently, when I submit Q-CHEM jobs on a cluster with SLURM resource manager, it sometimes will give the error:

failed standard license check on node24 SID 4F43DE1058

I just wonder if this means that there is some problems in my installation, or I should submit jobs one by one with a pause?

Thanks in advance!

Your Q-Chem installation uses node-locked licenses, and perhaps node24 was added or replaced after the initial license issue. A quick email with this information and your order number to will resolve the situation.

Thanks for your advice, I will email to the support.
