it is very hard to say anything about an error that basically means  
"you did
something very wrong with memory". It might also be a communication or
a hardware problem, rather than something related to the code itself.  
The
only code-related reason that could lead to a crash after 151  
iterations is a
memory leak, but there is no other evidence for it. If you look for  
"SIGSEGV 11"
on google, you will see that it is a quite famous, or infamous, error  
message...
