Aduit log Missing

Hi All,

we have notice the Audit log missing for successful asynchronous messages in production environment.

after looking at the issue indepth, i found a SAP Note relevent for this.. and understood that Audit logs for successful asynchronous messages are not persisted, the logs are stored in cache and cache entries are evicted - using a 'least recently used' (LRU) removal strategy - when the cache is full

1314974 - Successful asynchronous messages - audit log persistence

is there any confiuration parameter to change the cache sige?

Note: we don't want to change property that effect performance ( messaging.auditLog.memoryCache from the default to 'true' ).

Regards,

Pradeep A.
