[INSTRM-530] Possible failure in OBCP getFrames() internals

Thu, 8 Nov 2018 20:47:24 +0000

The g2sim3 server had an internal failure when allocating a new frame. Looks like a disconnection from the database server.

Is this a one-off thing? Should we be prepared for .getFrames() failures?

Finally, sorry for the impressively escaped log segment.
