Gunter, can you have a look ? Hello, I have spent quite some time to reproduce this problem, without success. Please confirm that this production is using a QGS. physics list. The problem then occurs in the hadronisation of a string produced by the QGS model modeling the interaction of a Kaon0L. I had rrun more than 10^6 Kaon0L through QGS in a simpler setup, and did not run into this problem. If you agree, I could make this a warning only? Gunter Fixed with tag had-hadronization-V07-01-00 |
In the ongoing mass production for the ATLAS physics workshop in June 2005, which is using Geant4.6.2.p01 (compiled against CLHEP1.8.2.1), there occurred a rare crash (core dump) in G4ExcitedStringDecay. The two reported cases both concern kaon0L's in Aluminium: -------------------------------------------------------------------------------- Crash #1: G4ExcitedStringDecay::EnergyAndMomentumCorrector - Warning Scale not unity at end of iteration loop: 5882.2396 957.77 6.1415993 Increase number of attempts or increase ERRLIMIT In src/G4ExcitedStringDecay.cc, line 130: ===> G4ExcitedStringDecay failed to correct...
