Machine is having
    CPU - Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz(8 core)
    RAM - 32GB
    HDD - 600 GB primary and other attached storage is there
    OS - Centos 6
    Freeswitch version - 1.3.10b ()

After calls get connected, we play audio files and we have voice app flows configured.
In the same machine only freeswitch is installed and JAVA application is there which connects to freeswitch to make calls.

We are using ISDN calling on the machine. So how many max sessions can freeswitch handle in practically?
The events from the ISDN network are processed very slower in the freeswitch. Sometimes the main Java app waits for the required event for any particular uuid, and gets other non required events from other uuids. We are filtering that, but after sometime we have to forcefully terminate that session because of non availability of event. This also leads to non-usage of full capacity.

Do you see the same problem if you write something small and hard-coded in c that uses libesl? That message about lost events typically only happens when the receiver can not process messages fast enough off the socket, and the queue fills up. This could be the fault of the java sockets, java esl library, or your code in java blocking while processing a message.
