OpenEdge client crashing

[sbjqad]

Recently I ran into problems rebulding the entire project. I saw an error like this popping up :

OpenEdge client ended with non-zero exit code. Check stdout0.log and clientlog0.log in /dr01/projects/po-receipt-aerpdevenv/.builder

I'm trying to figure out what's happening, but I can't find anything in stdout0.log or clientlog0.log. clientlog0.log is a big file, should I see an error at the endo of the file ? Or should I search for something in the file ? Anything else I can look at ?

It's usually the compiler that crashes the session. Do you see procore or protrace files in .builder/tmp?

These files always get cleared again after X number of lines..I need to find another way to save the logs...

I uploaded 2 files, one with the logs of the startup of the Language server and one with the logs after triggering a full rebuild.

I've sent you an email with extra details. You can post results here.

I replaced the jar you gave me. This is the version running :

[2026-01-16T08:46:01,881] [INFO] Starting OpenEdge LS/DA

But unfortunattely I still se the too many events error :

The WatchService that is used by the language server has a hard-coded limit of 512 events in Java 17 and 21 but it's possible to raise the limit in Java 25. Could you try downloading Temurin 25 (or any other OpenJDK 25), set the path to the Java executable in the LS settings and -Djdk.nio.file.WatchService.maxEventsPerPoll=2048 in the LS extra java args:

The JVM version is visible in the first lines of the LS output.
Increasing the value is required to monitor large directories. I guess your project with almost 200 propath entries and thousands of files is considered a large directory... Probably also a good candidate for the dependencies system introduced in the pre-release stream.
