eaked UDP ports from the logging using MDCSiftingAppender

["ayache.k" <ay...@gmail.com>]

Hi

Recently we started using MDCSiftingAppender to push logs into syslog and
we've noticed leaked UDP ports - see config set below. Here is a little bit
of context, we deploy around 20 bundles into apache Karaf and in one
occasion we've noticed around 26 thousands ports for syslog appender and
another same number for the file appender. It appears there is a UDP port
leak somehow but haven't figured out where in the code it's happening.

I am not sure if this is the best forum to get help with this. Just
wondering if anyone experienced this, any direction to relevant forums would
be also helpful.

Thanks

Ayache

You'd probably get a better response on the Karaf mailing list:
https://karaf.apache.org/index/community/mailing-lists.html
