Aditya commented on SOLR-4802:
------------------------------
I am not sure if this issue is active. But we recently had an incident where we
had to rollback to 3.5 on Production. There is seriously some issue with High
memory utilization in Solr with large multivalued field when retrieved.
Fetching large size multivalued field is causing System being unresponsive and
then eventually throw OOM.
I will try collect more data and update the Issue. Planning to raise a ticket
with Lucid Works
> Atomic Updated for large documents is very slow and at some point Server
> stops responding.

> I am updating three fields in the document which are of type long and float.
> This is an atomic update. Updating around 30K doucments and i always get
> stuck after 80%.
> Update 200 docs per request in a thread and i execute 5 such thread in
> parallel.
> The current work around is that i have auto-commit setup for 10000 docs with
> openSearcher = false.
> i guess that this is related to SOLR-4589
