Hello Eitan,
  Sorry for the long delay since i could not produce the error.


 I got the attached output after running the tf view_frames.

Initially for some amount of time it runs well but suddenly looses 
connectivity and starts giving error as:



[ERROR] 1283572338.978389000: Connectivity Error: Could not find a common 
time /base_link and /map.


[ERROR] 1283572339.176282000: Connectivity Error: Could not find a common 
time /base_link and /map.




As seen in pdf avg. transfer rate is: /odom : 21 Hz , amcl : 5Hz and 
/base_laser_link to /base_link tf transform by broadcaster is /99.xx
