AsyncOS alerts are generated whenever the Outbreak quarantine’s size goes above 5, 50, 75, and 95 of 
the maximum size. The alert generated for the 95% threshold has a severity of CRITICAL, while the 
remaining alert thresholds are WARNING. Alerts are generated when the threshold is crossed as the 
quarantine size increases. Alerts are not generated when thresholds are crossed as the quarantine size 
decreases. For more information about alerts, see 

AsyncOS also generates alerts when rules are published, the threshold changes, or when a problem 
occurs while updating rules or the CASE engine.

This section provides some basic troubleshooting tips for the Outbreak Filters feature.

Use the checkbox on the Manage Quarantine page for the Outbreak quarantine to notify Cisco of 
misclassifications. 

Bypassed file types are only excluded if a message’s only attachment is of that type, or in the case of 
multiple attachments, if the other attachments do not yet have existing rules. Otherwise the message is 
scanned.

Message and content filters are applied to messages prior to scanning by Outbreak Filters. Filters can 
cause messages to skip or bypass the Outbreak Filters scanning.
