Description

Hi All,

Under WIndows 8.1 and 2012, using the ZooKeeper C client 3.5.0, when running my ZooKeeper client, just after the ZooKeeper Client is connecting with the ZooKeeper server, the ZooKeeper server is generating a “caught end of stream” exception and deciding my is ZooKeeper client is not responsive: Zookeeper.c::check_events, line 2298: ESTALE. (see log below).

This problem systematically appears if the ZooKeeper DLL is NOT link statically with the Visual Studio debug version of the threaded runtime library.
This is reproducible 10/10

In clear, Windows ZooKeeper C client will works only if you link your ZooKeeper DLL with the switch "/MTd" (see VS Studio->Project->Configuration properties->C/C++>Code generation>runtime library)

Thanks

Bruno
