Hi Rishi,
beside turning off the logging for the affected Log-Factory in IS (“TNS.0000.”) by lowering the max log level which will be logged I do not see any chance to get rid of these messages.
When there were no changes to your implemenation there must have been changes to the webMethods components, i.e. applying Fixes or some config changes.
When there were no fixes applied recently and the configuration was not changed there must have been changes in the implementation.
Otherwise I do not have an idea why these messages should get logged out of a sudden.
When it relates to the database memory consumption (as TN requires a DB for working correctly) you should check the WmTN package for the wm.tn.archive:* services and run those on a regular time base (i.e. as a scheduled service) to remove old or outdated bizdocs.
See TN Built-In-Services Reference for details.
For the IS the memory consumption for just logging these messages should be minimal.
Regards,
Holger
