I just tried a query on a stock Solr example with rows set to 3000000000 
and got an error similar to the one you reported.

org.apache.solr.common.SolrException: For input string: "3000000000"

No mention of "int" in this error.  I'm wondering if that part was 
something you added to the email, not text that was actually in the error.

I was using Solr 8.5.1, the newest version I have downloaded right now.

This error also occurs in cloud mode. With distributed indexes, it could 
be perfectly acceptable to use a rows parameter that exceeds what a 
signed int can hold.  Performance would probably suck when using a value 
that high, but it would be acceptable.  Which smells like a bug in Solr.

I can tell you that using a value from uid in the rows parameter is 
almost certainly not the right thing to do.  That field would have no 
connection to rows.

Thanks,
