+# Allow that 16 coredumps are dispatched in parallel by the kernel. We want to
|
|
+# be able to collect process metadata from /proc/%P/ while processing
|
|
+# coredumps, and thus need to make sure the crashed processes are not reaped
|
|
+# until we finished collecting what we need. The kernel default for this sysctl
|
|
+# is "0" which means the kernel doesn't wait for userspace processes to finish
|
|
+# processing before reaping the crashed processes — by setting this higher 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.
