I'm enjoying using BaseX more than a year ago, thank you very much for all your help.

But then, suddenly, the HTTP server instance stops working while I'm executing a long time duration process: around 4 hours to generate some indexes. ( the process just crash and I have to restart it ).

This process was running daily for the last 14 months, without any problem.

My doubt is this: where or how may I get some information about what caused the problem?

Checking files inside /data/.logs I see only the RESTXQ calls and other minor logs, but nothing to give me a clue about the reason for the server crash.

I'm running BaseX 9.4 beta on a Debian machine. Here you have my settings: https://imgur.com/ucngBhY

Any suggestions?
