             Summary: 8.x memory issue
                 Key: SOLR-13617
                 URL: https://issues.apache.org/jira/browse/SOLR-13617
             Project: Solr
          Issue Type: Bug
          Components: update
    Affects Versions: 8.1.1, 8.1, 8.0
         Environment: {color:#000000}32-bit Ubuntu 18.04 LTS using OpenJDK 
10.0.2.{color}
            Reporter: Scott Yeadon


{color:#000000}I’m running Solr on 32-bit Ubuntu 18.04 LTS using OpenJDK 
10.0.2. Up until now I have had no problem with Solr (started running it since 
4.x), however after upgrading from 7.x to 8.x I am getting serious memory 
issues.{color}

{color:#000000}I have a small repository of 30,000 documents currently using 
Solr 7.1 for the search function. I attempted an upgrade to 8.1.1 and tried to 
perform a full reindex however, it manages about 300 documents and then dies 
from lack of memory (or so it says). I tried 8.1.0 with the same result. I then 
tried 8.0.0 which did successfully manage a full reindex but then after 
performing a couple of search queries died from lack of memory. I then tried 
7.7.2 which worked fine. I have now gone back to my original 7.1 as I can’t 
risk 8.x in my production system.{color}

{color:#000000}I increased Xmx to 1024m (previously 512m) but that made no 
difference, it may be some other resource than memory, but if it is, it isn’t 
saying so, and it’s such a small repository it doesn’t seem to make sense to be 
running out of memory, and 7.x runs fine
