WARN message
Hello,
I see lot of WARN messages in zookeeper.out. What is wrong/ how can we fix
it. This is ZK 3.4.10 with Solr 6.6.2.

Re: WARN message

In my case it was -Djute.maxbugger setting that solved it. There was a
larger file that needed to be propagated and the default (1MB) size was too
small.
Set the size to 4MB but try to keep it small, as I believe it is stuck on
the heap (comments?). Make sure when you add it is it being picked up by
the task (ps aux | grep -i zoo, and ps aux | grep -i solr).
You may want to see what is so big that it may need the larger size. In my
case this happens with Lucidworks Fusion.

Any insight what may be causing so many of these WARN messages?
