[Sciserver-users] Compute node restart - Wed the 24.1. at 9:00!

[Jonas Haase]

Dear SciServer Users

We currently seem to have an issue with the memory on several compute nodes. The symptoms are crashing/restarting kernels in Jypyter notebooks and random segmentation faults running scripts.
Since this happens both with old and new containers my assumption is that the problem lies with the underlying compute nodes.

I would like to restart all compute nodes ** Tomorrow morning Wed the 24.1. at 9:00 **
Could I please ask you to finish your running scripts and save progress until then?

Apologies for the short notice.

kind regards
Jonas
