You've talked recently about looking for STF money to upgrade the servers.
You might want to write up a postmortem when the bug is fixed, focussing on
improvements that are unlikely to happen without money.  Then you can say
"we had X hours of downtime, we think Y jobs will reduce that by Z%".

One thing for the postmortem - I don't know enough about these specific
programs to do much with the description provided.  And even if I did, I could
only offer prose hints at a solution.  But containerising these services would
let me replicate the server locally, and suggest solutions as normal patches
on the mailing list.
