I apologize if this has been asked before. I\'m using a 1Ghz eMac with 256MB RAM, using BOINC, and my model was working fine until it got to around timestep 6700. Around then, it started skipping one or more of the non-radiation timesteps, quite often, with no discernable pattern. I can tell the timesteps are actually skipped because the TS number skips, and it never comes back to them. I\'m just wondering if this is expected or abnormal.
