multi_run problem.

Which version are you using?
And which error did you face?

A long standing issue was with the number of thread hitting the limit of the system in such multi-run.
This is normally fixed in the latest LTS (or normal) version of the code.

Cheers,

Olivier

I am using version 3.1.0.

This is the error that i get,
    P1_gg_bbx

By the way, I just realized, I have asked the same. question long time ago and you already answer it. So i decide to just follow your advice from before from this linked.

Second option is to update your version of MG5aMC and it should be able to handle more consecutive run.

Hello Olivier,

After another 28th run, the multi_run for the second time gives again same error.

With the latest version?
