Thread lock starvation with RSemaphore on high concurrency with hundreds of locks (2)

This is a followup to #3573. We have now received the first user feedback from @jebeaudet which exhibits the same behavior as in the previous issue.

We have tried with Maven 3.8.x from the maven-3.8.x and Resolver 1.7.1 with Redisson’s RSemaphore. Several runs observe the same behavior. One thread tries to acquire a lock which is not held by anyone else and after the time is up (30 s) no lock is obtained. @jebeaudet privately provided me log files of those builds and I have distilled the lock workflows from it. Here is a sample:

lock_held	start_timestamp	end_timestamp	thread	lock_workflow	lock_type	lock_name

The write lock artifact:ch.qos.logback:logback-classic:1.2.3 is not held by someone, yet it fails. I can provide several SQLite databases which contain raw imported data, prepared data as well as joined by lock workflows/transitions. The thread dump of a hanging build looks always the same:

Redis version 6.2.4

Redisson version 3.15.6 on Java 11.0.11

Redisson configuration Nothing, but localhost....

PS: There is a similar issue with RReadWriteLock, but I will report this seperately.

[jebeaudet]

@michael-o I’ve ran it a couple of times and it’s all green on my end, gg!

[jebeaudet]

The holidays were good to me it seems, I had completely forgotten about this but thanks to @michael-o ping, I got around to it today.

I think I managed to reproduce it, it fails on my laptop and hopefully it’ll be the same for you.

1. Checkout https://github.com/jebeaudet/maven-redisson-3728
2. Build the custom mvn executable with mvn -DdistributionTargetDir="$HOME/app/maven/apache-maven-mosipov" clean package
3. Checkout https://github.com/jebeaudet/redisson-issue-3728
4. Run this magnificent script and check the output of the /tmp/semaphore-discriminating folder, you should have at least 1 build with a java.lang.IllegalStateException: Could not acquire write lock for xxxx exception :
