[zeromq-dev] Question about High Water and EPGM

[Jamie Stewart]

Hello,

We use ZeroMQ with EPGM and pub/sub sockets in our Java applications. We are running into a problem with one app, a slow consumer, when it receives bursts of traffic. Sometimes during the burst, the slow consumer stops receiving data from the sender altogether. I had assumed that this behavior happens if I set a high-water mark on the receive socket, but that is set to 0.

Are there cases with EPGM where a bursty sender and a slow receiver could cause the receiver to stop receiving, even if the high-water mark for the receive socket is set to 0? If so, do you have tuning advice?

Thank you very much,

   Jamie Stewart
