QRSH Interactive Session Termination When Pressing Keys During Scheduling (PTY Mode) #73
Description
Description
When submitting an interactive job using qrsh, if any key (e.g., Enter) is pressed during the message:
waiting for interactive job to be scheduled ...
the job will terminate immediately after being scheduled and will not enter the interactive session.
The qmaster log reports:
job <JOBID>.1 failed on host <EXEC_HOST> assumedly after job because: job <JOBID>.1 died through signal HUP (1)
If no key is pressed during scheduling, the session works correctly.
Additionally, when using -pty n, the issue does NOT occur. The problem happens only when using -pty y.
Steps to Reproduce
test.sh
#!/bin/bash
for i in {1..100}
do
echo $i
sleep 1
done
Run:
qrsh -pty y -now n -verbose -notify -j y -p 0 test.sh
Case A: No key pressed → Works normally

qmaster log:
job 3170911.1 died through signal HUP (1)
Case C: Using -pty n → Not affected
qrsh -pty n -now n -verbose -notify -j y -p 0 test.sh
Even if pressing Enter during scheduling, the interactive session starts normally.
