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
