2223173 - DB transaction logs growing up due to Java Mail Socket timeout

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:

"at java.net.SocketInputStream.socketRead0(Ljava.io.FileDescriptor;[BIII)I(Native Method)
 at java.net.SocketInputStream.read([BII)I(SocketInputStream.java:129)
