ORA-00018 when no where near session limit

Question

We have a database where we get ORA-00018 even though we have no where near the number of sessions configured in the database. We think we only have a couple of dozen sessions, and indeed select * from v$session shows only 33 rows.
Is it possible that there is a Linux limit or some other problem that is generating this error? Can I look at an error log to learn more?
Thanks for any help offered.

Hi,
I guess, that resource_limit parameter is not your problem
What is the current value for the sessions parameter ?
