Troubleshooting
AsyncOS for Web sends a critical email message to the configured alert recipients when the internal 
logging process drops web transaction events due to a full buffer.
By default, when the Web Proxy experiences a very high load, the internal logging process buffers events 
to record them later when the Web Proxy load decreases. When the logging buffer fills completely, the 
Web Proxy continues to process traffic, but the logging process does not record some events in the access 
logs or in the Web Tracking report. This might occur during a spike in web traffic.
However, a full logging buffer might also occur when the appliance is over capacity for a sustained 
period of time. AsyncOS for Web continues to send the critical email messages every few minutes until 
the logging process is no longer dropping data.
The critical message contains the following text:
Reporting Client: The reporting system is unable to maintain the rate of data being 
generated. Any new data generated will be lost.
 
If AsyncOS for Web sends this critical message continuously or frequently, the appliance might be over 
capacity. Contact Cisco IronPort Customer Support to verify whether or not you need additional Web 
Security appliance capacity.
