Errors only in generations of large event number
Hi MG5 experts,
We've been encountering an error that seemed to mostly happen when generating a relatively large number of events (in our case several thousands).
Additionally, this error didn't seem to happen every time (we got occasional success by just trying more), neither for every parameter.
Specifically, we were varying only two parameters, mzdinput and number of events.
And this error seemed to only occur when we syntactically allow off-shell bosons (generate g g > h Z Zp > l+ l- l+ l-) and set mzd relatively large (while not when we enforced bosons to be on-shell).
I have always tried with clean shells and directories, made sure loading the athena version that has been working (asetup 19.2.5.31,here), and tried on different clusters (LXplus, cluster local at our university with Singularity, and BNL cluster), but the error persisted despite all those factors.
And the only factor that seemed to lead to higher frequency of getting the error was going to greater number of events.
The error message is as the following:
-------
