Qsub: cannot connect to server

Hi,

I’m experiencing a new error in running the RNS of ACCESS-rAM3. My task is stuck at install_ec_startdata job, with its status being submit-retrying. I checked the job-activity.log, it shows the following error:

[jobs-submit cmd] cylc jobs-submit --utc-mode --host=gadi.nci.org.au --remote-mode -- '$HOME/cylc-run/u-dx548/log/job' 20011108T1800Z/install_ec_startdata/03

I ran this suite successfully last week before the gadi maintenance. Does anyone know how to resolve this?

Thank you

@reyhan.respati Simplest first step is to check if you have restarted you persistent sessions. Do you want to run persistent-sessions list and confirm you have done so? They stop when Gadi goes down.

Something’s wrong in the connection between persistent sessions and PBS, NCI have been notified

Hi @cbengel,

I have restarted my persistent session this morning. I have also checked its name matches that in my ~/.persistent-sessions/cylc-session.

Thank you

People are telling me the qsub issues from persistent sessions are now resolved
