Errors when running with a different topology file + incast flows with conweave as load balancer

[sana-mahmood]

Hi,

I am trying to run an experiment with conweave load balancer. I am using the attached topology file with 8-ary fat tree topology. The links between the servers and switch are 10G and between switches are 40G. There is also incast traffic, that I am generating using the attached file, this is in addition to the background traffic. I am using the following command to run the simulations

I am coming across a couple of errors when trying to run,
1- Sometimes simulations terminate right when they are started with the following assertion fail:
assert(tx_md.flagExpired == true);

2- Some experiments run for sometime and terminate with the following error

Both the errors seem to be related to the internal working of conweave, I am unsure what could be causing it. It would be great if you can point me towards the right direction. I have also attached the config file in case there is some issue with the configuration.
