Simulation freezes

[Maria Nelago Kanyama]

I am running a simulation but after some minutes of running the simulation freezes. what could be the problem? it doesn't give any warning or any error . i am using Omnet 5.0++ Inet framework 3.4

Maybe a memory problem? Check the memory consumption of the OMNeT process.

Also, try to run your simulation under the debugger to see if it spits out an error message.

it doesn't spit out an error message at all.i usually run my code in debug mode. maybe its memory problem, how do i sort that out?

You could check whether at the freezing point you still have free
physical memory. If not swapping to disk has begun and can be really
slow, especially if you record the eventlog.

Does "top" (Linunx) or the windows task manager show any CPU activity or
do the memory numbers change?

Hope that helps!

And running your simulation in debug mode and running it with GDB/debugger are different things, but I assume that you mean the latter (running it with a debugger).
