Hi, I’m running Solr on Ubuntu 18.04 (32-bit) 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.
I have a small repository of 30,000 documents currently using Solr 7.1 for the search function (for the last two years without issue). I attempted an upgrade to 8.1.1 and tried to perform a full reindex however, it manages about 1000 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. Has anyone else had these issues with 8.x? Note that I did increase 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. Scott.
