The max open cursors include necessary cursors to run direct sql submitted

Hi,
We're currently getting a lot of ORA-1000 errors (max open cursors exceeded) on Oracle 8.1.7.4.
I tried looking at v$open_cursor and saw the following:
1* select sid, count(*) from v$open_cursor group by sid order by count(*)
desc
SQL> /
SID COUNT(*)
---------- ----------
9 43
8 38
11 38
27 38
This seems inconsistent with our open_cursors parameter of 255.
Is there something I'm doing wrong, or something else I can check to try and determine if this parameter is set incorrectly perhaps, or am I looking at v$open_cursor incorrectly. Part of the difficulty is that our application connect to the database via 24 database connections - all sharing load. My understanding though is that each of the 24 connections should allow 255 cursors to be open and our highest connection is only showing 43 in v$open_cursor.
Any suggestions are greatly appreciated as people are getting anxious.
Regards,
Mark.
