I know of thousands of cores on a single Solr instance. Operationally
there's not problem there, although there may be some practical issues
(i.e. startup time and the like).

What does your Solr log show? Two popular issues:
OutOfMemory issues
Not enough file handles (fix with ulimit)

 But without more specific info about what Solr reports in the log
it's impossible to say much.

Best,
Erick
