- Troubleshooting
- Agent and System Manager cannot communicate with each other
- Agent complains that idds has not been enabled, yet lsdev shows /dev/idds is present
- Agent does not start on system boot
- Agent halts abnormally, leaving ids_* files and message queues
- Agent host appears to hang and/or you see message disk full
- Agent needs further troubleshooting
- Agent does not start after installation
- Agents appear to be stuck in polling status
- Agent displays error if hostname to IP mapping is not registered in name service
- Aggregated alerts targets or details field are truncated and the same aggregated alert has several entries logged in the IDS_ALERTFILE
- Alert date/time sort seems inconsistent
- Alerts are not being displayed in the alert browser
- Buffer overflow triggers false positives
- Duplicate alerts appear in System Manager
- Getting several aggregated alerts for the same process
- GUI runs out of memory after receiving around 19,000 alerts
- The idsadmin Command needs installed agent certificates
- The idsadmin Command notifies of bad certificate when pinging a remote agent
- IDS_checkInstall fails with a kmtune error
- IDS_genAdminKeys or IDS_genAgentCerts does not complete successfully
- IDS_genAdminKeys or idsgui quits early
- Large files in /var/opt/ids
- Log files are filling up

pathnames_X, programs_X
You can use these properties to filter out race condition alerts
generated when a specified program modifies the file
reference of a privileged program for a particular file. See
“Type II: Path Names/Programs Pairs” (page 116) for a
detailed description of these property pairs.
Alerts generated by this template
The following alerts are generated by the Race Condition template:
• “File Reference Modification” (page 127)
• “Privileged setuid Script Executed” (page 128)
File Reference Modification
Table A-7 lists the alert properties that the File Reference Modification template generates and
forwards to a response program when the file reference in a privileged program is modified
unexpectedly.
