[erlang-bugs] erlang,hd,[[]]

[Vitaliy Kulchevych]

Hi, all!
I'm using cpu_sup for monitoring os of erlang node. Sometimes I catch crash:

{badarg,[{erlang,hd,[[]],[]},{cpu_sup,get_uint32_measurement,2,[{file,"cpu_sup.erl"},{line,282}]},{cpu_sup,measurement_server_loop,1,[{file,"cpu_sup.erl"},{line,585}]}]}
