Since Friday I cannot start Rose GUIs on PUMA with the following error message popping up:

Do I need to change any settings or account/login details? Many thanks in advance!

There are a few older tickets with similar issues; these were usually caused by running out of disk space. Is it possible to delete some old data and try again?

Hi Dave

I tried that already. I had > 1000MB in my home directory and thought that might cause the problem, but the error still occurs after reducing to ~700MB. Or is that still too much?

That is what I would have done. I think that you've deleted enough, but there's possibly something fiddly which happened during the period in which you were over the limit. If you run ps -flu mtodt there are several old python processes from last Friday. Perhaps the next thing to do is to kill all of these (and all non-essential processes), then log out and back in again, and start afresh.

Sometimes brute force solutions can work.

Hi Markus,

Your quota looks okay but just in case I have increased it from 1GB to 3GB. Try again and see if that helps. If not have you used ssh -X to get into puma? Sometime logging out of your computer completely and starting again helps.

Hi guys

I'v killed the python jobs, logged out and back in again, and can open Rose now. Thanks a lot for helping me immediately!

No probs. If you don't mind then I'm closing the ticket- feel free to open it if you get other problems later on.
