+Patch Package: OTP 22.3.4.24
+Git Tag: OTP-22.3.4.24
+Date: 2021-12-21
+Trouble Report Id: OTP-17796
+Seq num: ERIERL-729
+System: OTP
+Release: 22
+Application: erts-10.7.2.16
+Predecessor: OTP 22.3.4.23
+
+ Check out the git tag OTP-22.3.4.24, and build a full OTP system
+ including documentation. Apply one or more applications from this
+ build as patches to your installation using the 'otp_patch_apply'
+ tool. For information on install requirements, see descriptions for
+ each application version below.

+
+ OTP-17796 Application(s): erts
+ Related Id(s): ERIERL-729, PR-5473
+
+ Responsiveness of processes executing on normal or low
+ priority could suffer due to code purging or literal
+ area removal on systems with a huge amount of
+ processes. This since during these operations all
+ processes on the system were scheduled for execution at
+ once.
+
+ This problem has been fixed by introducing a limit on
+ outstanding purge and copy literal requests in the
+ system. By default this limit is set to twice the
+ amount of schedulers on the system. This will ensure
+ that schedulers will have enough work scheduled to
+ perform these operations as quickly as possible at the
+ same time as other work will be interleaved to a much
+ higher degree. Performance of these operations will
+ however be somewhat degraded due to the overhead of
+ enforcing this limit compared to when using a very
+ large limit.
+
+ This limit can be set by passing the +zosrl command
+ line argument to erl, or by calling
+ erlang:system_flag(outstanding_system_requests_limit,
+ NewLimit).

+ ---------------------------------------------------------------------
+
+ Note! The erts-10.7.2.16 application *cannot* be applied
+ independently of other applications on an arbitrary OTP 22
+ installation.
+
+ On a full OTP 22 installation, also the following runtime
+ dependency has to be satisfied:
+ -- kernel-6.5.1 (first satisfied in OTP 22.2)
