I beg to differ. Normally, a wrong entry in the semaphore in the /etc/system file will cause the DB to be unable to start up.
If the error you see happens a couple of days after restarting the DB, most likely it is due to fragmentation shared pool.
These are the things you can try in order:
1) Check for SQL that are not using binding variable, get your developers to change them to binding variable. This will reduce the number of distinct SQLs required to be cached in the shared_pool.
2) Increase the shared_pool and reduce the shared_pool_reserved size. This will allow more distinct SQLs to be cached in shared_pool and at the same time, reduce the usage of shared_pool_reserved. (This will help if the fragmented shared pool you are facing is at the shared_pool_reserved)
3) Check Oracle metalink for bugs related to this oracle error. I do know that Oracle 9i has a bug related to this, not too sure on Oracle 8i.

jifty::dbi::handle::oracle
Jifty::DBI::Handle::Oracle(3pm) User Contributed Perl Documentation Jifty::DBI::Handle::Oracle(3pm)
NAME
Jifty::DBI::Handle::Oracle - An oracle specific Handle object
SYNOPSIS
DESCRIPTION
This module provides a subclass of Jifty::DBI::Handle that compensates for some of the idiosyncrasies of Oracle.
METHODS
connect PARAMHASH: Driver, Database, Host, User, Password
Takes a paramhash and connects to your DBI datasource.
database_version
Returns value of ORA_OCI constant, see "Constants" in DBD::Oracle.
insert
Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted.
build_dsn PARAMHASH
Takes a bunch of parameters:
Required: Driver, Database or Host/SID, Optional: Port and RequireSSL
Builds a dsn suitable for an Oracle DBI connection
blob_params column_NAME column_type
Returns a hash ref for the bind_param call to identify BLOB types used by the current database for a particular column type. The current
Oracle implementation only supports ORA_CLOB types(112).
apply_limits STATEMENTREF ROWS_PER_PAGE FIRST_ROW
takes an SQL SELECT statement and massages it to return ROWS_PER_PAGE starting with FIRST_ROW;
distinct_query STATEMENTREF
takes an incomplete SQL SELECT statement and massages it to return a DISTINCT result set.
