I am running a GLPK model that is sequentially started from a frame program

In this contex, what is a frame program?
What OS are you running?
Unfortunately, I get sometime error when opening the .csv files.
Here is an example:
/
csv_driver: unable to open BOM.csv - Permission denied
allocation.mod:113: error on opening table tab_BOM
glp_mpl_build_prob: invalid call sequence
Error detected in file ..\src\glpapi14.c at line 93/
I do not get this error at each call of the Java model (one error after
approx. 50 calls). Moreover, these errors do not occur in a deterministic
manner, they cannot be reproduced. I each run of the Java program they occur
at another place.
Looks like a thread issue to me.
Do the open and close occur in different threads?
Perhaps the open is attempted before the close has gone through.
