[rabbitmq-discuss] ** Too many db tables **

[Farshad Meshkinpour]

Hello,

I get the following error when one of the nodes in the cluster lost its
connectivity (RabbitMQ *2.8.6* on Erlang *R14B04)*.  After that the cluster
became useless until we restarted all nodes in the cluster.  Few questions:

1. Do we need to increase the ETS table limit from 1400?  we have several
thousands mirrored queues and several hundreds of consumer/producers.
2. How does rabbit uses ETS table (e.g. one per queue, one per connection)?
3. Is there a command to show how many ETS tables are in use?
4. What is the current timeout for detecting other nodes in the cluster and
can it be increased?

Thanks,
Farshad
