It appears that we can connect to the DB Server itself as I get “connection received” and “connection authorized” – but when trying to access the DB itself, several errors are raised
(see below).
I am assuming that some internals are no longer consistent – the file “global/11801” for instance really does not exist on the system.
Questions:
1.
Is there any way to recover from this (backup is unfortunately rather old)
2.
What are possible causes? I’d like to prevent this from happening on my production servers.
** I am aware that we are on older releases, and yes, we plan to migrate to more current releases “soon” ™ …
Thanks in advance.
