Can't connect to ZooKeeper server with the C client library from Solaris:
connect() call fails.
-----------------------------------------------------------------------------------------------
Key: ZOOKEEPER-1123
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1123
Project: ZooKeeper
Issue Type: Bug
Components: c client
Affects Versions: 3.3.3
Environment: Client: Solaris 5.10, x86 machine.
Server: Linux Fedora 14
Reporter: Tadeusz Andrzej Kadłubowski
I have a C app that runs on Solaris and connects to ZooKeeper which I run on
Linux (just a single server instance, that's just a development setup).
Upon calling zookeeper_init() I get logs that say connect() call fails.
TCP-wise the client sends RST packet instead of the third part of the three-way
handshake. Traced client syscalls below.
Sometimes the client is able to establish a connection - after half an hour of
trying, or even longer.
Logs

The client logs:

What does work:
===============
Using Java client on the same Solaris machine works without any problems.
Connecting to the Linux server using C client library on Linux works OK (though
I tested it within one box, via loopback interface).
