Switching to a uniprocessor OS causes the problem to stop.. This seems to point pretty solidly to a race condition in the SMP version of the OS. Thanks Is this reproducable on fedora or a RHEL variant? If not, I will close as current release. It's so old that it can be closed.. FYI.. despite buying support for these machines, this is the FIRST contact I've had with ANYONE since I opened the problem in 2002!!!! I'm REALLY disapointed with Redhat's support in this regard! |
From Bugzilla Helper: User-Agent: Mozilla/4.75 [en] (X11; U; SunOS 5.7 sun4u) Description of problem: When running a script that loads an executable image on a dual 1.2ghz processor Athlon system, the program will fail with a segmentation fault on the load, if the file system isn't mounted. If you mount the file system first, the load works every time. I suspect that there may be a bug in mount on dual processor machines. I have a core file, if you need it. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. place a large executable on an nfs exported file system which is handled by the automounter (nis maps) 2. run a script that runs the executable.. if the file system is unmounted, it fails. 3. If you run it again, before the automounter unmounts it, it runs fine. 4. to provoke it again before the automatic unmount, do a hand unmount of the file system. Actual Results: /apps/synopsys/cur/linux/syn/bin/dc_shell-t: line 4: 1513 Segmentation fault (core dumped) ${exec_name} -tcl_mode -r ${synopsys_root} "$@ Expected Results: the task should run Additional info: I've tried to add "hard intr" to the mount to see if that helps. No change. I was not able to reproduce the bug on 7.2. (The third party application is certified on 7.1)
