jemalloc library not found

Description

On starting my Teku it reports

2024-10-10 15:01:32.267 INFO  - jemalloc library not found.

However, jemalloc is installed (and Besu is using it):

$ apt list 'libjemalloc-dev'
Listing... Done
libjemalloc-dev/jammy,now 5.2.1-4ubuntu1 amd64 [installed]

I really don't remember whether this matters or not. Just reporting in case it does.

Thanks for the report!

Looks like this was recently introduced as part of updates related to RocksDB. I'll take a guess and say that it should not affect normal operation, and there is nothing to worry about. We'll take a look into it!

It doesn't affect operation at all. It is just an informative log. I'll have a look to see why it isn't detecting its presence.
