Hello,
I am trying to get help on this past 2 days . We are using default request response Patten for communication between different modules on the server after first deployment on GCP cloud, while load test we encounter issue where for multiple requests at a time to a modules stops receiving request at some point of time . Following are things we checked for this. 1. Sample zmq req- response application as mentioned in below email (was able to reproduced the issue, responding module hangs and does not accept further requests.) 2. Tired adding monitoring for socket event in sample ( didn’t help). https://www.npmjs.com/package/zmq 3. Found no issues with memory and CPU usages . 4. Tried Setting up ZMQ_HWM = 0, ZMQ_SWAP etc. for the sample program didn’t helped. http://api.zeromq.org/2-1:zmq-setsockopt 5. Currently looking at http://zguide.zeromq.org/php:chapter4 for reliable request response Patten . Am I checking in right direction ? please suggest.
