[erlang-questions] start_timer and timer fired lag

I'm usgin nksip library for working with sip protocol and in my virtual
machine (windows -> virtualbox -> ubuntu) I'm observer very strange
behaviour with erlang:start_timer [1]. Some time in common test, the timer
fires with lacency with hundred milliseconds.

I've check, there is no messages in queue, msacc says there is no problem
with schedulers and whole system is idle, erlang:monitor(time_offset,
clock_service) show that time in virtual machine flows monotonically.

I wonder, how can I find out why erlang behaves strange sometimes?

Erlang version is:

$ erl
> Erlang/OTP 20 [erts-9.2] [source] [64-bit] [smp:4:4] [ds:4:4:10]
> [async-threads:10] [kernel-poll:false]
> Eshell V9.2  (abort with ^G)
