Arvind,
I have just finished looking into your "Failed to set the Samle Rate" message (
0.9z-7-3 Sample Rate not set ) and there is no way I can let that message happen. I looked in there regarding the topic here ... Why ? because the log file tells that it stops in there ...
By now I built in another few log messages, but that is for the next time.
Okay, so IMO your SFS is too low to let it go OK by guarantee. But, don't ask me where it stops working (re the log files) because I never looked into that. And, I did not do that because all is very critical anyway. Thus, it can happen here too. Notice though that it has been reported that it helps when Garbage Collection (Settings) is deactivated (yes, I asked you before how that is set, but I forgot).
Can't say more ...
(but see your other topic about the Sample Rate)
