</div>Just a blind guess:<br>
�EMFILE (errno 24 - "too many file descriptors opened")<br>
<br>
Maybe you have too many files opened? You can see<br>
the numbers using management plugin.<br>
<br>
On linux you can increase the limit by running<br>
`ulimit -n <number>`, but you have to be root.<br>
<br>
Usually, rabbit tries to optimize the usage of file descriptors,<br>
in case when you have many queues it can mean that rabbit<br>
opens loads of files. But as you open more and more network<br>
sockets the number of opened files should drop.<br>
<br>
This may not be a case for jsonrpc - AFAIK it doesn't have<br>
code for dealing with usual rabbitmq file descriptor<br>
counters. Theoretically in that case, when you have many<br>
files opened by jsonrpc - you may hit the wall.<br>
<br>
I suggest run the management plugin and checking the<br>
file descriptors counters, trying to get understanding about<br>
jsonrpc plugin usage. And increasing the file descriptor<br>
limit if necessary.<br>
<br>
Cheers,<br>
