[Beowulf] problem with binary file on NFS

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!

Jörg
