We are seeing an issue on our Solr Cloud 7.3.1 cluster where replication
starts and pegs network interfaces so aggressively that other tasks
cannot talk. We will see it peg a bonded 2GB interfaces. In some cases
the replication fails over and over until it finally succeeds and the
replica comes back up. Usually the error is a timeout.
Has anyone seen this? We've tried adjust the /replication
requestHandler and setting:
<requestHandler name="/replication" class="solr.ReplicationHandler">
<lst name="defaults">
<str name="maxWriteMBPerSec">75</str>
</lst>
</requestHandler>
but it appears to have no effect. Any ideas?
Thank you!
