Python web application stops being able to find databases

[GoogleCodeExporter]

What steps will reproduce the problem?
1. I am running a web application written in Python and Flask (this uses 
mod_wsgi and Apache). After a short amount of time, the db2 driver begins 
returning 'supplied connection object parameter is invalid' even though the 
connection is closed each time. Further investigation into the tracebacks 
reveals the following:

[Fri Mar 07 09:55:06 2014] [error]     conn = 
ibm_db.connect(<dbname>,<username>,<password>)
[Fri Mar 07 09:55:06 2014] [error] Exception: [IBM][CLI Driver] SQL1013N  The 
database alias name or database name "<dbname>" could not
 be found.  SQLSTATE=42705 SQLCODE=-1013

What is the expected output? What do you see instead?
Connection drops after a short amount of time. An Apache restart fixes this.

What version of the product are you using? On what operating system?
Red Hat 6.4
Python 2.7
ibm_db-2.0.4.1-py2.7-linux-x86_64.egg

Please provide any additional information below.
Other services on the host seem to work fine with the installed DB2 client even 
the ibm_db module returns this issue.
