Is audispd-remote the only plugin running off audispd? A slow plugin back up everything. You might try disabling other plugins that are active to see if this helps things. Ultimately, the problem is events are arriving faster than they can be sent to plugins. You might also try boosting the priority a little assuming all other plugins are tuned off. I think it defaults to 4. Also, how big of a storage are you giving audispd-remote? If all other plugins are disabled and you still get this, then there might be a need for a bigger queue. -Steve > Changing the auditd to forward doesn't seem to help.
