RedHat 5 - pstack and gdb
I'm chasing a weird bug and I have a clue, but I don't know what it means.
I have a program that uses OpenGL and Motif running on RH5 workstations.
On two machines, the program takes 5 minutes or so to come up, when on all
the other machines (five of them), it comes up immediately. All seven
machines are loaded the same and have the same hardware.
So here's my clue. If I run the process on either of the two "slow"
machines under gdb, or do a pstack while it is hung, it comes up right
away. I know this must be telling me something important, but I cannot
figure out what.
Any ideas?
