hi
I am using Tossim simulator (micaz platform). I want to test a routing protocol
in large scale networks. but when I create large networks I get "*** glibc
detected *** /usr/bin/python: malloc(): memory corruption: 0x000000000282e060
***"
First I thought that it happens because of the maximum number of nodes in the
network (which is specified by -fnesc-nido-tosnodes option) I corrected it and
increased it but still I get the same thing.
Then I realized that the number of lines in "noise.txt" is less than my nodes.
so I copied the lines so that it matches with the number of nodes. But it
didn't work either.
I tracked the compiling process again and I realized that in app.c file created
by making micaz (while compiling) there is a "noiseDate" array which is bounded
to 1000 elements. 1000 is the maximum number of nodes that at this moment I can
have.
I checked the files to find the parameter which is initialized by 1000 but I
couldn't find it.
here is the python code I am running:
print "test1"
noise = open("noise.txt", "r")
print "test2"
lines = noise.readlines()
print "test3"
print n
for line in lines:
str = line.strip()
#print "test6" , str
if (str != ""):
val = int(str)
for i in range(0, n-1):
t.getNode(i).addNoiseTraceReading(val)
# for n=1200 nodes after 827 steps "*** glibc detected ***
/usr/bin/python: malloc(): memory corruption: 0x000000000282e060 ***" happens
# t.getNode(i)
print "test7", i
print "test4"
for i in range(0, n-1):
t.getNode(i).createNoiseModel()
print "test 5"
and here is the output of compiling

I really don't know where to look for its problem so please if any one has any
clue for it guide me.
Thanks for your attention.
