How reproducible:
Occurs any time graphs attempt to generate


Steps to Reproduce:
1.Install Spacewalk on CentOS 5.3 x86_64.
2. Enable monitoring.
3. Monitor server (to populate data).
4. Attempt to generate graphs from said data.
  
Actual results:
No graph. The following error is reported in catalina.out:
