Reproduction

This seems like an issue with the log4j API with JUL, since it should ideally create an ExtendendLogger but that is null.

-Djava.util.logging.manager=org.apache.logging.log4j.jul.LogManager
-DAsyncLogger.RingBufferSize=32768
-Dlog4j2.contextSelector=org.apache.logging.log4j.core.async.AsyncLoggerContextSelector

These are the additional settings for the same

[anuragagarwal561994]

Is there a chance that the weakref in case of AsyncLogger is getting garbage collected?

This is to better signify that the exception originated because of log4j, actually if the static fields in class fails one time, then when called the second time, it will give NoClassDef found

[anuragagarwal561994]

Seems related to #3143

[ppkarwasz]

@anuragagarwal561994,

Thank you for the report.

The LoggerRegistry implementation was changed in 2.25.0-SNAPSHOT. Can you check if that fixes your issue?
Our snapshots are located in the https://repository.apache.org/snapshots/ Maven repository (see also our download page).

[anuragagarwal561994]

Actually this is ocurring very rarely, like in 3 days it occurred on only 1 pod out of 100-200 so, I am not sure if I will be able to test it properly in production.

Actually this is ocurring very rarely, like in 3 days it occurred on only 1 pod out of 100-200 so, I am not sure if I will be able to test it properly in production.

If it occurs only in production, we'll try to find another reproducer. It is better not to test in prod. 😉

[anuragagarwal561994]

Yes, I think there is a reprodcuer attached in the linked issue

[ppkarwasz]

@anuragagarwal561994,

Does [version 2.24.2 (RC1)](https://lists.apache.org/thread/n0kk7op8tmg0mojtvh3y8lo2c8s51gs8) solve your problem?

[anuragagarwal561994]

From the diff I checked it seemed like it will, but since the issue happens on random pods in production I will only be able to check it after deployment.

[ppkarwasz]

Closing this, since release 2.24.2 should fix it.
