NUMERICAL DIFFICULTIES WITH INTEGRATION ROUTINE means, well, it's having problems with the numerical integration!
You basically have a few choices:
1. Change the relative tolerance, TOL, from 5 to a number requiring fewer significant figures, e.g. 3
2. Try a different numerical integration algorithm, e.g. if you are using ADVAN6, try ADVAN8 or ADVAN9.
3. Your model is too complex, make it simpler.
