Hi All,

Currently we are using PUB-SUB and PUSH-PULL .  Our server is on Linux  (
C/C++ ) and clients are on JAVA Android.

Server Version : ZeroMq 3.3.0
Client Version : JeroMq 3.2.2

*Design  we are using : *
Client queries server using PUSH.
Server receives this query on PULL.

Now server responds to the client via PUB.
On the other hand clients are waiting with SUB ids.

*Issues : *

   1. After sometime some of the subscribers are NOT receiving the message,
   when client is re-started , they start getting the message .
   2. After some time , we have observed , subscribers start receiving the
   old message multiple times , where as server has published different
   message .

Both the issues are frequent , please let us know How to fix the issue .

Thanks And With Regards
Ranjeet Kumar
