However, if other explicit ODE-solvers have no issues and your solution is always progressing at more or less constant rate, then it does point towards msadams. But let's first try to rule out problem-specific numerical issue. Could you please observe what happens in about 100 evolve_apply steps just before tripping? There is example in the manual how to run evolve_apply manually (without driver). I'd be interested to know if solver step length changes a lot just before tripping or not.

The msadams solver apparently requires a driver?
