RabbitMQ 3.5.7

RabbitMQ 3.5.7 is primarily a bug fix release.

Server

Bug Fixes

• Fix a race condition that could prevent nodes from stopping.

  GitHub issue: rabbitmq-server#465

• file_handle_cache:clear_read_cache/0 no longer silently fails.

  The function is mean to be used with rabbitmqctl eval in environments where in-process buffering of file data is enabled.

  GitHub issue: rabbitmq-server#436

• Default RABBITMQ_PLUGINS_DIR value on Windows should be calculated as relative to RabbitMQ server installation directory, not RABBITMQ_BASE.

  If you override RABBITMQ_BASE, you may need to copy plugins from %RABBITMQ_BASE%\plugins to the plugins directory under RabbitMQ installation.

  GitHub issue: rabbitmq-server#433

• When rabbitmq-server failed to start due to an unreadable config file, exit code was 0

  GitHub issue: rabbitmq-server#464

• Overriding RABBITMQ_LOGS and RABBITMQ_SASL_LOGS on Windows prevented node from starting.

  GitHub issue: rabbitmq-server#375

• Some startup code bits assumed IPv4 is enabled in the environment

  GitHub issue: rabbitmq-server#117

• More robust disk monitor, fewer errors logged.

  GitHub issue: rabbitmq-server#91

• rabbitmqctl forget_cluster_node no longer attempts to impersonate live (reachable) nodes.

  GitHub issue: rabbitmq-server#470

• rabbitmq-plugins was using an incorrect env variable.

  GitHub issue: rabbitmq-server#451

Enhancements

• RAM watermark can be configured as an absolute value in bytes (just like with disk space monitoring):

  [{rabbit, [{vm_memory_high_watermark, {absolute, 1073741824}}]}].
