Symptom
The db transaction logs are slowly growing up and it is observed that there are threads active for a long time using the db transaction logs.
If we create a db application snapshot we identify the application which is consuming more resources.
If we check the thread activity (by creating a thread dump) at this moment, we can see that the application thread looks similar to this:
