rabbitmq is terminating and closing connection

[si...@minddotss.com]

I placed rabbitmq in EC2 instance with ubuntu os. starting it is working after that i access rabbitmq through API's using php and put in cronjobs. Then After it is continuously terminating connection everyday.I changed rabbitmq server process in to 204000,and i enable handshake timeout in configuration.But it is not restarting.

Here is the logs:

Reason:Channel error on connection <0.21153.18> (172.31.19.214:52674 -> 172.31.19.214:5672, vhost: '/', user: 'test'), channel 1:

This is not RabbitMQ terminating but a particular node component, a disk space monitor.

In reasonably recent versions this means that RabbitMQ won't know how much disk space

there is available on the node, that's it.

According to the log your clients never perform AMQP 0-9-1 handshake. One common reason for that

is that you try to connect to a TLS port with a client not configured to use TLS or vice versa.

Thanks Michael klishin for your quick response.

Actually In my project,we are using direct rabbitmq API's  to send data in to Queue.And in consumer side it is processing successfully After some time(night times)rabbitmq it is disconnecting.

And im using following API to send data.

http://54.66.50.11:15672/api/exchanges/%2f/amq.default/publish 

with authentication and php Curl method is using to send json data.

And one more thing ,i changed memory set limit,file discriptor count,And also im trying to enable in conf file,at that rabbitmq is not restarting.

Last thing im running around 20 API's daily by using cronjob in ubuntu.

Publishing over HTTP API is not commonly used and is available only as a last resort measure.

Consider using a "real" PHP client library [1].

ok,But in my project Andriod app will direct hit that API and send data to queue.And by using crontab im executing  consumer file ,inserting data in to database.

RabbitMQ Java client works on Android. Note that RabbitMQ client connections are supposed to be

long lived, which may or may not be easy or optimal for various mobile apps

" One common reason for that is that you try to connect to a TLS port with a client not configured to use TLS or vice versa."

from ur response,these TLS port related issue will come when we hitting directly API.

And somewhere i got,cronjob will stop rabbitmq in the middle of the night(unix based time system).Is there Anything related

[Michael Klishin]

Your node hits a resource alarm, which is quite visible in the logs.

See http://www.rabbitmq.com/alarms.html and solve that problem first.

Hi micheal,

my system have these memory configuration,is it suitable for rabbitmq memory limit

root@ip-10-0-0-163://# free

             total       used       free     shared    buffers     cached

Mem:       1016324     946160      70164       3196       1636      32236

-/+ buffers/cache:     912288     104036

Swap:      1023996     926348      97648

Its Around 1GB. Let me know how much RAM is required for Rabbitmq.

[Michael Klishin]

It depends on your workload.
