Sometimes coreutils commands fails
and I'm looking a clue what could be root cause or where to debug

SETUP:

1.       System Device is ROUTER

2.       Silicone has 2 CPUs of ARM9

3.       coreutils (GNU coreutils) 8.24  - 2015

4.       File-System NFS over Ethernet/USB

5.       High Ethernet traffic with high CPUs' loading (overloading)

6.
PROBLEM:
Sometimes (hardly reproduced) coreutils commands (for example - "ls", "date")
Stop to work and return the below error

/usr/bin/coreutils: error while loading shared libraries: /usr/lib/libgmp.so.10: unexpected PLT reloc type 0x40

DEBUG NOTES:

-          Traffic stopped CPUs are in~100% IDLE

-          The NFS is working and available

-          No any Out-Of-Memory seen, a lot of free memory

Thanks for helping
