Description Leonard den Ottolander 2001-09-26 23:07:12 UTC
Description of Problem:
 When restarting portsentry after an attack CPU usage peeks (top, about 
75% CPU usage on this 1GHz Pentium system). This condition goes on (at 
least for minutes) until portsentry is restarted another time.
 Not sure if this is a portsentry or maybe an init script issue.

Version-Release number of selected component (if applicable):

How Reproducible:

Steps to Reproduce:
1. Launch an attack from a system (fe telnet 6667). Repeat if
necessary (twice in this configuration).
2. Issue "service portsentry restart" on the attacked system.
3. Run top to monitor CPU load

Actual Results:
CPU load peak.

Expected Results:
Normal CPU usage.

Additional Information:

This state only occurs when KILL_RUN_CMD is not specified.
Specifying a KILL_RUN_CMD solves the issue.
Maybe catch an empty KILL_RUN_CMD?

Closing as WONTFIX due to end of life of the Power Tools product line. Please
open a new bug report under the Red Hat Linux product if the component is still
included in the base Red Hat distribution.
