Kristian, your example is rather complex and somewhat time consuming even on fast computers, so it is not easy to track your problem down to its original reason. However, what is clear to me is that this is definitely *not* not a problem of deSolve and most likely even not of optim, it is j

Dear R-users, I'm running an MLE procedure where some ODEs are solved for each iteration in the maximization process. I use mle2 for the Maximum likelihood and deSolve for the ODEs. The problem is that somewhere along the way the ODE solver crashes and I get the following error message: DLSODA-
