You do not provide enough information to help solve the problem, so I 
will be general:

#1 you could have a problem with your stack
#2 you could be trashing your buffer
#3 you could have a corrupted data byte that is stopping your Rx routine 
from working....
#4 you could be ending up in an endless loop....

If you can post your code we can look over it.
