Solr version:

{noformat}

8.4.1 832bf13dd9187095831caf69783179d41059d013 - ishan - 2020-01-10 13:40:28

{noformat}



Java process:

{noformat}

java -Xms100G -Xmx200G -DSTOP.PORT=8078 -DSTOP.KEY=ardsolrstop
-Dsolr.solr.home=/ardome/solr -Djetty.port=8983
-Dsolr.log.dir=/var/ardendo/log -jar start.jar --module=http

{noformat}

Run on a powerful server with 32 cores, 265GB RAM.

The problem is that time to time it start to get very slow to update solr
documents, for example time out after 30 minutes.

document size is around 20k~50K each, each http request send to /update is
around 4MB~10MB.

According to jstack for the thread state, lots of BLOCKED state.

thread dump log is attached.

Any hint would be appreciate, thanks!
