Research direction

Reproduce the crash with the attached omnetpp.ini, .ned, demo.xml, and .json files, focusing on simu5g::GtpUser in MultiOperatorMultiMec.upf_A.gtp_user. Start from the reported check_and_cast() failure at about 7.1 seconds and determine why an inet::Indication is received where an inet::Packet is expected. Done means the 40-second multiMEC simulation completes without this runtime error.

Description

I'm running a simulation a multiMEC scenario over a 40 s, but crush after few seconds 7-9s. The msg error show is:

A runtime error ocurred:

check_and_cast(): Cannot cast (inet::Indication*) ERROR to type 'inet::Packet*' -- in module (simu5g::GtpUser) MultiOperatorMultiMec.upf_A.gtp_user (id=217), at t=7.1020052264s, event #315291

Launch a debugger with the following command?
opp_ide omnetpp://dsp/debugger/attach?pid=55211

Attached the code file:

  • omnetpp.ini
  • .ned
  • demo.xml
  • .json
