Disable or limit erlang dumps on RabbitMQ

[kulbalgis]

Hello
I am facing issue when erlang dump is generated because erlang process run out of memory. Generated dump is big as RAM and it not only filling up /var/log/ mount but it is useless in general because explanation of a failure is in the first we lines of the dump. I tried to set erlang variable via rabbitmq-env.conf but couldn’t make it work. How can disable or limit erlang dumps?
ERL_CRASH_DUMP_BYTES

Using ERL_CRASH_DUMP_BYTES. rabbitmq-env.conf likely filters out non-RabbitMQ related variables. Just set it in the env for the effective user any other way.

Thak you for the reply Michael, looks like this did the trick.
RABBITMQ_SERVER_ADDITIONAL_ERL_ARGS='-env ERL_CRASH_DUMP_BYTES 0'

[michaelklishin]

ERL_CRASH_DUMP_SECONDS set to 0 is another way of disabling crush dumps.

It should work to set ERL_CRASH_DUMP_BYTES in rabbitmq-env.conf, but you would have to export it like this:

export ERL_CRASH_DUMP_BYTES=0

I've added a small section on this to the Runtime guide.
