There is no packet loss, dstat shows everything is fine with disk, RAM, etc. I tried increasing keep alive for nginx connections but that did not seem to help.

Right now, agent keeps asking /proc/diskstats all of the time. strace shows that syscall 'nanosleep' is used 72% of time. I will test disk but from the first glance vmstat shows there are no blocking processes. Also, I will try to play with nginx keep alive directive and timeouts tomorrow and post an update here.
