Jorg,
It might be that the executable is corrupted by
NFS during delivery to that node. Once that
happens, the cached copy can stay bad. You can
check it by comparing md5sum results on that node
and on the node that owns the original.
There's a thread back in December of last year
titled "NFS Read Errors" that tells about my
experience. I never found a solution except to
get rid of the Redhat 9 systems....

Dear all,
I have a problem with a selfwritten program on my small cluster. The cluster
nodes are PIII 500/800 MHz machines, the /home is distributed via NFS from a
PIII 1 GHz machine. All nodes are running on Debian Etch. The program in
question (polymc_s) is in the users /home directory and is running on all
nodes but one. I get the following error messages on that particular node
(node4):
ldd polymc_s
not a dynamic executable
file polymc_s
polymc_s: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for
GNU/Linux 2.4.1, dynamically linked (uses shared libs), for GNU/Linux 2.4.1,
not stripped
strace ./polymc_s
execve("./polymc_s", ["./polymc_s"], [/* 18 vars */]) = -1 ENOMEM (Cannot
allocate memory)
+++ killed by SIGKILL +++
Process 2177 detached
I am currently running memtest, no problems thus far. Other programs like the
BOINC stuff (I am using that for stress-testing) are ok. Reuti already
suggested to do:
readelf -a polymc_s
which gave identical outputs on node4 and node3 (both are PIII 500 MHz
machines). I am somehow stuck here, has anybody got a good idea? Running the
software locally does not make any difference, i.e. same errors as above.
Changing the file permissions did not mend it either. I am aware these are
old nodes, but for the purpose they are ok.
All the best from Graz!
