Server possibly crashing due to too many threads?

Which version of Lucee are you both running?

TBH I wouldn’t be so concerned about how much RAM, the question is, why are you seeing I’m assuming, stuck threads?

I’d recommend trying out 5.3.8.170 as it’s 5.3.8 is about to go stable and it’s super solid.

There have been some additional fixes since 5.3.8 RC1 which address some memory issues with sessions.

Graphs are pretty but don’t tell you much, this is what the thread report looks like in my Free Performance Analyzer plugin, you can sort the table by clicking on the headers and the stack traces give useful clues to what’s causing problems.

That is why we moved all of our WP sites behind Cloudflare. I helps stop a lot of junk traffic.

Just a big thank you to Zac for the performance tool.

Facing memory issues again so going to try to use this to explore why contexts can’t handle Lucee using up to only 1GB of memory off-peak.

Does anyone know if this still works in Lucee?
If so, where do I set this variable? I am running a default Lucee install (lucee-5.4.3.15) on an Ubuntu server.

Thanks for any help.
