Description David Cook 2024-04-09 02:24:18 UTC 
background_jobs_worker.pl runs its tasks in child processes which return their memory to the OS when they complete.

es_indexer_daemon.pl runs everything in itself which means if it needs to allocate a large amount of memory for an indexing job, it will hold on to that memory allocation for its entire process life.

--

I've got an es_indexer_daemon.pl which is using over 1GB of memory. Once it's done with its indexing activity, I'm going to restart it to get it back down to a more reasonable amount of allocated memory. 

I reckon we should be forking off child processes to do the worker. We don't need many. We just need 1 that is short lived so that it can return the memory back to the OS.

In prod, we seem to restart the services often enough this isn't a problem, so going to close this one for now.
