[rabbitmq-discuss] RABBITMQ_SERVER_ERL_ARGS on Windows

Tue Sep 10 16:41:03 BST 2013

Oops, my mistake. The reference to RABBITMQ_SERVER_ERL_ARGS is indeed in
the rabbitmq-service.bat:

set ERLANG_SERVICE_ARGUMENTS= ^
-pa "!RABBITMQ_EBIN_ROOT!" ^
-boot start_sasl ^
-s rabbit boot ^
!RABBITMQ_CONFIG_ARG! ^
+W w ^
+A30 ^
+P 1048576 ^
+Q 65536 ^
-kernel inet_default_connect_options "[{nodelay,true}]" ^
!RABBITMQ_LISTEN_ARG! ^
!RABBITMQ_SERVER_ERL_ARGS! ^
-sasl errlog_type error ^
-sasl sasl_error_logger false ^
-rabbit error_logger {file,\""!LOGS:\=/!"\"} ^
-rabbit sasl_error_logger {file,\""!SASL_LOGS:\=/!"\"} ^
-rabbit enabled_plugins_file \""!RABBITMQ_ENABLED_PLUGINS_FILE:\=/!"\" ^
-rabbit plugins_dir \""!RABBITMQ_PLUGINS_DIR:\=/!"\" ^
-rabbit plugins_expand_dir \""!RABBITMQ_PLUGINS_EXPAND_DIR:\=/!"\" ^
-os_mon start_cpu_sup false ^
-os_mon start_disksup false ^
-os_mon start_memsup false ^
-mnesia dir \""!RABBITMQ_MNESIA_DIR:\=/!"\" ^
!RABBITMQ_SERVER_START_ARGS! ^
!STAR!

Cheers,
