By default global does not take any actions to restore
a fully connected network when connections are lost due
to network issues. This is problematic for all
applications expecting a fully connected network to be
provided, such as for example mnesia, but also for
global itself. A network of overlapping partitions
might cause the internal state of global to become
inconsistent. Such an inconsistency can remain even
after such partitions have been brought together to
form a fully connected network again. The effect on
other applications that expects that a fully connected
network is maintained may vary, but they might
misbehave in very subtle hard to detect ways during
such a partitioning.
In order to prevent such issues, we have introduced a
prevent overlapping partitions fix which can be enabled
using the prevent_overlapping_partitions kernel(6)
parameter. When this fix has been enabled, global will
actively disconnect from nodes that reports that they
have lost connections to other nodes. This will cause
fully connected partitions to form instead of leaving
the network in a state with overlapping partitions.
Note that this fix has to be enabled on all nodes in
the network in order to work properly. Since this quite
substantially changes the behavior, this fix is
currently disabled by default. Since you might get hard
to detect issues without this fix you are, however,
strongly advised to enable this fix in order to avoid
issues such as the ones described above. As of OTP 25
this fix will become enabled by default.

Fix memory leak when tracing on running on a process
that only handle system tasks or non-message signals
(for example process_info requests).

Fix Erlang monotonic time on MacOS. Previously used OS
monotonic time primitive on MacOS is buggy and will not
be used anymore. It has been replaced with usage of
another OS monotonic time primitive that does not
appear to be buggy.

OTP-17905 Application(s): kernel
Related Id(s): ERIERL-732, PR-5740
A net_tickintensity kernel parameter has been
introduced. It can be used to control the amount of
ticks during a net_ticktime period.
A new net_kernel:start/2 function has also been
introduced in order to make it easier to add new
options. The use of net_kernel:start/1 has been
deprecated.
