    Interpreting the message "error processing end".

    Edwin Babadaglian Newbie

      Greetings,

       

      I'm currently investigating an incident that yielded numerous occurrences of the following message in HTTPD error_log file:

       

          [Mon Feb 21 08:09:44 2011] [error] [client xx.yy.zzz.229] proxy: error processing end, referer: http://host.domain.net/someApp/

       

       

      My research so far has me suspecting a few possible factors:

       

      1. Unexpectedly high application latencies tha might have breach some timeout thresholds.

      2. A high-volume of NotSerializableException occurrences, perhaps contributing to #1.

      3. AJP-related anomalies, with potential work-around through connector timeout properties.

      4. Application-specific characteristics involving HTTPD interactions (ajax, etc).

      5. Version of Tomcat container in use (6.0.20).

       

       

      My hope is to get a better idea of what to investigate. As of yet, I have not been able to reliably reproduce this symptom but have a lot of options to consider at this point.

       

       

      Many thanks for any insight into this error.

       

      Edwin
