Solr 8.9.0 zookeeper WARN org.apache.zookeeper.ClientCnxn

Hi ,
after upgrading solr from 8.4.1 to 8.9.0 I sometimes get this WARN

WARN  - 2021-10-21 18:40:05.202; org.apache.zookeeper.ClientCnxn; An
exception was thrown while closing send thread for session
0x20000087c0d5288. => EndOfStreamException: Unable to read additional data

if I run
- an upconfig /opt/solr/server/scripts/cloud-scripts/zkcli.sh -cmd upconfig
.....
- an healthcheck /opt/solr/bin/solr healthcheck -c collname -z
zkhost:zkport.....

Could I ignore this WARN  ??

Thanks

Hopefully someone else will confirm this, but I believe this is something you can ignore.
