I am running Koha 24.05.03.000 on Ubuntu 24.04 with 8 vCPU cores and 32 GB of RAM.

Recently I found that the VPS was running at 100% CPU usage and discovered that memcache was not running. The high CPU usage would cause it to crash. To solve this, I started memcache and confirmed it was running and followed the instructions at https://wiki.koha-community.org/wiki/Koha_Tuning_Guide. It seemed to run better for a short time. But it is back up to 100% usage, which slows it down considerably. When I run top to see what is using the CPU, it shows many opac-search.pl running on many processes. Is that normal? Are there other things I can do to reign in CPU usage?
