-
Yes, Gary is mistaken. MongoDB may log to SLF4J but then that is bridged to
Log4j which then tries to log it to MongoDB and it all starts over again.

[~ggregory], If I understood correctly for loop to happen, both

-
I am guessing there is a loop between slf4j and Log4j as the MongoDB client
depends on slf4j:
[https://search.maven.org/artifact/org.mongodb/mongodb-driver-sync/4.5.0/jar]
This can be configured to work as documented here:

Omer U commented on LOG4J2-3396:
Will we be able to run mongodb appender for root logger? May be mongodb
appender could check and postpone/buffer logs coming from itself, until
connection is established?
Current behavior is interesting. Application stalls for 30+ seconds, then
application starts, and logging works.

[jira] [Commented] (LOG4J2-3396) ERROR Recursive call to appender mongodb with spring boot root logger

Ralph Goers commented on LOG4J2-3396:
-
I will have to look at the example but I am 100% certain the issue is that the
MongoDB client is using Log4j for logging. Those logs are then routed to the
MongoDB appender and you have an endless loop.
The fix is to provide a logger that matches what MongoDB uses and route those
message to a different destination.

Would you provide a PR on GitHub with a test that demonstrates this issue? That
would be the simplest for me to debug.
