Hi,
I've got a staging environment running, with two signers signing a
staging version of the .is zone (~115k records).
The staging servers are configured with 2 GB RAM and 4 CPU cores,
running on FreeBSD 12.2.
We've experienced that knot crashes because the server runs out of
memory. The zone is configured with:
zonefile-sync: -1
zonefile-load: difference-no-serial
journal-content: all
One of the signers, after an hour of running is showing 215 MB resident
memory used.
The other signer, that's been running for a whole day is showing 1582 MB
resident memory.
I attached a screenshot showing the amount of memory used over a period
of time, and the graph shows that the amount of memory used very
suddenly increases.
I assume the servers are using a lot of memory for the journals, but I'd
like to understand why the sudden increase in used memory, and what to
expect about needed memory?
