You are using Symantec Security Information Manager (SSIM) 4.7.0 or greater and you notice that in the on box sesa-agent.log there are two errors in the sesa-agent.log that repeat about every four minutes:
2011-07-04 12:12:26,670 INFO [Logging] Response code = 404, URL = http://127.0.0.1:80/sesa/servlet/support?action=update
2011-07-04 12:12:26,672 INFO [Logging] Response code = 400, URL = http://127.0.0.1:80/sipi/servlet/Sipi_Configuration_Loader?action=update
Every time the Event Agent tries to update its configuration, it tries to contact the above 2 URL's which are not available in SSIM 4.7.x
These are not fatal errors, they can be safely ignored and will be addressed future update to the Symantec Event Agent. These lines will occur in the Symantec Event Agent v4.7.1 and earlier.
