- OK, let me try again.
-
- I have a 700k program compiled from Fortran which runs fine on
- 2 DECstations 3100 both with 8Mb
- of memory one with Ultrix 4.0 the other with Ultrix 4.1. However, when I
- tried to run the same program on a DECstation 3100 with 20Mb of memory
- with Ultrix 4.0 it core-dumped.
-
- Running dbx shows that the program stopped at line 3, which is a
- comment line (so are the 2 lines proceeding it). The source code has not
- been changed since the compilation. In other words, it core-dumps
- before it starts executing the first statement, possibly while it's
- loading. I guess this is paging related. How do I find out
- and fix it? Specifically, how do I find out about the configuration
- regarding the paging space the system is using? And how do I change
- that?
-
- Here is some detail:
-
- Machine 1: 8Mb mem, Ultrix 4.1, one scsi disk, swap on rz0b
- This one works
-
- Machine 2: 8Mb mem, Ultrix 4.0, two scsi disks, swap on rz1b
- This one works
-
- Machine 3: 20Mb mem, Ultrix 4.0, two scsi disks, swap on rz1b and rz4b
- This one core-dumps
