Inquiry Regarding Inconsistent Error in Simu5G 1.2.2 Scenarios with MEC #195

Closed rimsayegh closed 4 months ago

rimsayegh commented 4 months ago

I am currently working with Simu5G version 1.2.2 and have encountered a recurring issue that I hope you can assist me with.

The problem arises in scenarios involving MEC, specifically with multiMecHost, SingleMecHost, and when adding more than two MECs. An error consistently appears. However, this error's occurrence is erratic; it happens intermittently, even when the same code and parameters are used. This inconsistency is observed both on Windows and Ubuntu platforms.

The error is: Invalid signal signalID=419 -- in module (ServiceRegistry) MultiMecHost.mecHost2.mecPlatform.serviceRegistry (id=679), at t=1.047366760966s, event#12307

Could you please provide some insight into the potential cause of this issue? Understanding the root of this problem is crucial for my ongoing work.

Please try to apply the same changes that you find in the latest commit - here: https://github.com/Unipisa/Simu5G/commit/a28aba469a785fcd166d2fd0c41408605d86d4b6 - or clone the updated master branch from the repo. Then build the code, run the simulation again and see if the problem arises again.

Thank you for your guidance. I followed your instructions, and everything is working perfectly now.

Additionally, we are interested in running two applications, WarningAlert and VideoStreaming, simultaneously in the same scenario. Until now, we have been unable to execute both applications in parallel in the same scenario. Could you provide any insights or guidance on anyway to do so?

Thank you once again!
