Hi everyone, Just following up on this. Would be good to know who I could reach out for some paid support regarding this, if this is deemed more appropriate.

Running 10.11.14-MariaDB, Apache/2.4.66, perl 5 version 36 - unsure if these are useful or whether this perl version is an assumed dependency version of the Koha version.

Hi David,
Sure thing, apologies!
Koha 24.11.14 (I updated to this in the last couple of weeks hoping there was a bugfix) on Debian Bookworm LTS, shipped with the 6.1.159 kernel (linux-support-6.1.0-42).
The issue persists on reboot.

Hi Justin, there's some information missing from your message that could help a remote diagnosis: - Basic system information - Koha software information - Actions already taken, e.g. system restart, Koha restart, Plack restart
Thanks!

Hey everyone,
Was hoping for some guidance on where to start diagnosing an increase of CPU, disk and network usage on our Koha instance. The culprit is seemingly plack (/etc/koha/plack.psgi) & the Koha perl API (usr/share/koha/api/v1/ app.pl).
No changes were made, updates nor configuration, and according to our monitoring started on the 23/03.
Have gone from sitting at around 0% CPU idle, to ~20% on the 23rd and now averaging around 70%.
Any ideas on where to start?
Thanks in advance,
