Event admin blacklisting?
I'm having an issue where events stop getting delivered to a bundle the cause of which appears to be the following? Everything works perfectly until this occurs? What is the timeout it's complaining about? This is 4.2.0 btw.

AFAIK there is also "org.apache.felix.eventadmin.Timeout=0" to disable the
timeout handling at all.
Another approach would be that your event handlers only take the event and
add it to a blocking queue (e.g. LinkedBlockingDeque).
You could use another thread that handles the elements added to that queue.
I assume in that case you return very fast.
At leat we don't see any blacklisting anymore (without the timeout=0 option
but with delegation the event handling to a separate thread).

I'm still having some issues with this. I have a 2 (maybe 3) event handlers in my app and I've recently started having blacklist issues. I don't know what's causing it since the handlers themselves haven't changed and should run very quickly, probably under a 10 millis or so in most cases.
Anyway, per Ben Graf's response below, I updated file org.apache.felix.eventadmin.impl.EventAdmin.cfg with the following line:
org.apache.felix.eventadmin.IgnoreTimeout=com.medline.*
Given the description of the property, I expected this to cover all the event handlers in my app but I'm still seeing at least one of the handlers get blacklisted. Is the syntax wrong or are there any other recommendations regarding this?
Thanks in advance,
Scott

Hi Scott,
timeout for blacklisting is 5000ms. (see
