If Solr has GC pauses greater than 15 seconds, zookeeper is going to assume
node is down and hence would send it into recovery when node comes out of a
GC pause and reconnects to zookeeper.
You should look into keeping GC pause as short as possible.
Using G1GC with ParallelRefProcEnabled has helped me a lot, but you may
want to come to settings that work best for using trial and error.
If you are not using MMapDirectory try switching to it. It helps by keeping
index off the heap.
Also check if issue SOLR-9310 affects you, since your replicas are going
into recovery, I am afraid it is doing full index copy than just picking up
the delta.
