Actually, I just translated 2 jiffies because HZ is 100 in default cavium config.
You can find that in "arch/mips/configs/cavium_octeon_defconfig".
And i have been using this value over 1 year in octeon board without problem.

Have you been writing to EEPROMS? Their erase/write cycle might be
longer. But I am not forcing you to change the value, just giving some
suggestions.
