Error files when using multicore runs and psn

Dear All, We are using psn version: 3.4.2 together with NONMEM 7.2.0 on a Linux Sun Grid Engine (SGE). When using multi-cores run on SGE, it happens sometimes that NONMEM returns a log file where the "MONITORING OF SEARCH" starts and nothing is reported. Looking into the psn directory, I found files which have the name of my script file + an extension made of letters and numbers that contains an error message that is not shown on the log file. For example my nm-tran script file is run003.mod and my log file run003.lst ends with: MONITORING OF SEARCH: Stop Time: Wed Jul 10 21:05:18 CEST 2012 Then I recover a file named run003.mod.o9501 in run003/NM_run1 directory created by psn. Sometimes this file contains an explicit error message, sometimes more cabalistic information as: WARNINGS AND ERRORS (IF ANY) FOR PROBLEM 1 (WARNING 2) NM-TRAN INFERS THAT THE DATA ARE POPULATION.
