Logstash stops often

Hi,

Since a long time ago my logstash is stopping. The log shows this error:

I understand that the problem deals with throttle.
What can i do to fix this? it is productibeless as i should restart logstash to make it work again.

My cnf file is huge, so if you need let me know where to upload it.

Thanks
