Yogesh: Please do not hijack threads. The original poster requested information about socket timeouts. True “upgrade” was mentioned, but it was a completely different issue.
Kshitij: There’s not much information to go on here. It’s possible you were running close to the timeout limit before and “something” changed just enough to go over that limit. I’m a bit confused though, you talk about commands like reload while indexing. What _exactly_ are you trying to do? Details matter. One thing that did changes was “schemaless” became the default. This causes reloads when Solr is indexing docs and comes across fields for the first time. I personally don’t recommend “schemaless”, so what happens if you turn that off? If you’re manually sending reloads, you might try doing them async. That said, you must start from a fresh index with _no_ documents in it when you upgrade more than one major version.
