bq. I meant to ask whether there is a high probability that that could be the correlated cause for the issue.
Yes, I do tend to be pedantic on occasion, a personal failing ;) bq. Do you know why Solr itself isn't able to recover or is that to be expected with allowing such deep pagination. The general problem isn't deep paging itself, but the fact that in your case it generates an OOM. After an OOM there is no way to recover; the state of the program is unknown. This is pretty much true of all Java programs, which is why there's an OOM-killer script you can configure. That won't help your situation since you'll probably dive right back into an OOM, but at least it doesn't continue to try to work with a program that's in an unknown state.
