[AMPL 2886] Problem with CPLEX timelimit

[hessam-4]

Hi All,

I have a problem with timelimit in CPLEX. I used the command "option
cplex_options 'timelimit=21600'; " in my AMPL which forces the cplex
to stop after 6hours and returns the best results found by then. But
I'm running my AMPL for 12hours and the program is not still stopping.
The only thing I see is:

ILOG CPLEX 11.210, licensed to ".........", options: e m b q use=1
CPLEX 11.2.1: timelimit=21600

Any idea about the problem?? I know that there is no problem with my
ILP code, because with other data input files it works fine, but for
one of my inputs it never stops!!!

Thanks,
Hessam

PS: This group is always a big help for me.

I found the problem. It seems the memory used in my program is more
than the available memory on the running server.
