Hi! Debugging an issue (a few hundred processes hanging) I used "echo w >/proc/sysrq-trigger". When viewing the journal I found out that it's incomplete, saying (grep Missed): Jun 01 12:33:10 h18 systemd-journald[3256]: Missed 3990 kernel messages Jun 01 12:33:10 h18 systemd-journald[3256]:

A few questions: 1) What causes this? 2) How can systemd know how many messasges were missed? 3) Can I avoid that problem?
