(with echo t > /proc/sysrq-trigger) Hard to tell at what time syslog-ng did freeze, but chances are big it's somewhere between 435.x and 591.x when nilfs stops sending/getting events. The collectd instance in D-state is most probably the one that wants to write data to RRD file. At least it looks very easy to reproduce! Just restarting collectd a few times and enabling its rrdtool plugin.
