RE: [NMusers] error (157) forrtl: severe

[Mark Sale - Next Level Solutions]

Joachim,  This is probably a file access error, from Fortan/OS, not from NONMEM.  Does NMTRAN run?  Does the compiler run?  Does nmlink6 run (do you get link.lnk)?  Do you get an executable? Does NONMEM start then stop?  If you get the executable (nonmem.exe or fsubs.exe), then the error is with file access in the NONMEM itself. Don't know which file, but if NMTRAN runs it isn't the (NMTRAN) data set, still could be FDATA, FCON, FSTREAM, FRECORD, any of the FILE? (but probably not) or an MSF.  Fortran should close all the files when it exits, by any method (e.g., if it crashes).   Cou! ld conceivable be a library file from the compiler as well.

These crashes occur with very simple (ADVAN2) and also with rather complicated  (ADVAN5, ADVAN7) models. They can be avoided when models are reformulated with ADVAN6 TOL=5.  Of course with ADVAN6 all models run slower and this is not really a solution of our problem. We run NONMEM VI without the recent bug fixes in a "naked" fashion on the server, and with "wings" on the PCs. Our compiler is Compaq Visual Fortran (latest version). We appreciate your thoughts on that. __________________________________________ Joachim GREVEL, Ph.D. MERCK SERONO International S.A.
