Varun Thacker created SOLR-8539:
-----------------------------------
Summary: Solr queries swallows up OutOfMemoryErrors
Key: SOLR-8539
URL: https://issues.apache.org/jira/browse/SOLR-8539
Project: Solr
Issue Type: Bug
Reporter: Varun Thacker
Fix For: 5.5, Trunk
I was testing a crazy surround query and was hitting OOMs easily with the
query. However I saw that the OOM killer wasn't triggered. Here is the stack
trace of the error on solr 5.4:

So HttpSolrCall#sendError needs to throw an OOM exception instead of swallowing
it and sending back and error in the response.
Once I made HttpSolrCall#sendError throw an exception on OOM I still hit the
following stack strace
{code}

So is Jetty not propagating the OOM Error back to the JVM?
