# processes are not reaped until we have finished collecting what we need. The

# kernel default for this sysctl is "0" which means the kernel doesn't wait for

# userspace to finish processing before reaping the crashed processes. With a

# higher setting the kernel will delay reaping until we are done, but only for

# the specified number of crashes in parallel. The value of 16 is chosen to

# match systemd-coredump.socket's MaxConnections= value.
