When submitting new jobs to Z/OS agent, the jobs do not submit.
The file specified for COMMQ on the Z/OS server is full.
Restart the Z/OS agent with this option:
S zos_stc, PARM=CQFORMAT
Create a new file for COMMQ and then re-start the agent using that file.
Note: Provide adequate space to the file so that it does not fill up frequently.
