The ubuntu was created on VM in the same computer with the windows version but I have also tried with another computer and faced the same problem too.
Looks like the program can't read addr because when I tried print addr in gdb it said 'error reading variable: Cannot access memory at address 0x14'
Could you guys please provide me some help or tips on this problem? Right now I'm not sure if the problem is about the codes or my PC system but from my trials I have a sense that the simulation crashed when the servers are trying to form a simplemesh overlay.
Thanks in advance.
With this information is difficult to reproduce the problem.
Versions, configuration, something like this is necessary

This time I tried on ubuntu 16.04 LTS still got the same error in gdb
0x00000000004f3c06 in IPvXAddress::set (this=0x534c440, addr=...) at ../../inetmanet-2.0/src/networklayer/contract/IPvXAddress.h:137

[Config CDN-P2P]
description = DenaCast (CDN-P2Ptracker, DenaCastApp, MPEG4Camera, MPEG4Player)
network = oversim.underlay.inetunderlay.InetUnderlayNetwork2
I can run this example without problems
I have stopped the simulation at the second 5000 and I cannot reproduce the problem
There is a difference in the configuration that I am using
InetUnderlayNetwork2.connectivity = 0.8
InetUnderlayNetwork2.connectivity = 1
In other case the network has isolated nodes.
Thank you for your attempt to reproduce my problem sir.
Did you
run with CDN-P2P Tracker, CDN server and Overlay[2] sir? Initially the
omnetpp.ini file didn't include denacast.ini when I ran without denacast.ini (No CDN-P2P Tracker, CDN server)
I received no error but when I included denacast.ini and add these
lines in omnetpp.ini
[General]
include ./denacast.ini
*.underlayConfigurator.gracefulLeaveDelay = 15s
*.underlayConfigurator.gracefulLeaveProbability = 1.0
sim-time-limit = 200s
**.numTiers = 2
**.accessNet.channelTypes = "oversim.common.denacast_channel"
**.queueType = "inet.linklayer.queue.DropTailQueue"
**.tier1.queue.frameCapacity = 100000
**.ppp[*].queue.frameCapacity = 100000
The crash happens when the components are trying to join overlay. My network looks like this

I have run a fresh installation downloading the code currently in github, I have run the simulation CDN-P2P but I cannot reproduce your problem
Dear Alfonso sir,
Thanks again for your effort.
From what I've seen in your sim. Can you try putting CDN-P2PTracker, CDN Servers in your scenario like in denacast.
Freshly downloaded code from github doesn't include denacast.ini but in my case
I've included denacast.ini in the omnetpp.ini shown below

If you include these file you need to modify the configuration files, there are parameters in the denecast that are incompatible with the configuration that are by default.
You should change the ini files only.
Denacast was based in a previous version of Oversim than 20121206
I am no sure, the denacast is a bit obsete, it is based in an older version of Oversim

Actually I have been trying to change the ini files from the start but even when I manually add Simplemeshmodules overlay churns based on the OverSim documentation in omnetpp.ini file, the segmentation fault still occurs.

Dear Alfonso sir,
Recently, I have just tested again on Windows 10 32 bit OS and I still receive the same error. So there is a very high chance that I even have installed the wrong version of inetmanet and OverSim but I think I installed it the right way because I can run other samples.
Or I have configured .ini files wrong myself.
Could you please send me your configuration files (omnetpp.ini, denacast.ini and default.ini) so that I could try simulate the corrected configuration and get the result?

I tried to run CDN-P2P -- DenaCast (CDN-P2Ptracker, DenaCastApp, MPEG4Camera, MPEG4Player)
the overlay I select on my .ini file is SimpleMeshModule (set by default)
but for the config ini files I used the same as ini files from denacast branch provided in my attached files before

What particular scenario?
It is possible that the problem could be due to a configuration field that is not correct.
I will try to check, but I am a bit busy
What particular scenario?
