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.
