Interesting, I haven't seen the automatic upgrade fail yet. Perhaps running the second step (3.5.0 -> 4.10.2 using the 4.10.2 jar) manually, too, will reveal what the problem is.
1) Anyway, I didn't check how sophisticated the upgrade logic is. You seem to have only upgraded one of the cores manually (1.3.0 -> 3.5.0). Either upgrade them all manually or upgrade them all automatically. 2) Try to run Maven with debug flags 3) Download lucene-core-4.10.2.jar manually and run IndexUpgrader and CheckIndex on your index version 3.5.0 to complete the second step. 4) If all else fails, assuming it's really a memory / index size issue (but I don't think it is), you could shard the statistics core with DSpace 3.x (Solr 3.5.0) and try to upgrade each shard individually (auto-upgrade of all shards at once should work, too, but I'm not certain).
