Meenal,

You're probably running out of CPU cycles.  

FYI, you can control how many simultaneous FM xmitters are running with
fm_tx.py using the -n option.

If you run some kind of CPU monitor applet, you should be able to keep
an eye on this.  I'm using KDE and I think the applet I'm running is
called ksysguard.
