I have 32-bit and 64-bit clients built under windows,
linux, and solaris with v1.3.5 libmosquitto (no threading or srv).
On the 64-bit windows client (only), publishing
occasionally fails. I created a C
example that simply publishes 1000 messages (using
new/connect/publish/disconnect/destroy).
Source here: http://pastebin.com/hK9vZ53H
The 32-bit windows version always publishes all 1000
messages. The 64-bit version never
publishes all 1000, it will fail to publish between 5 and 50% of the messages.
Looking at the server logs, for failed messages:
1415308846: New connection from ::1 on port 1883.
1415308846: New client connected from ::1 as
mosq/Rt82I0s`3N2r3Tv]Ni (c2, k60).
1415308846: Sending CONNACK to mosq/Rt82I0s`3N2r3Tv]Ni
(0)
1415308846: Socket error on client
mosq/Rt82I0s`3N2r3Tv]Ni, disconnecting.
whereas for successful messages:

This is specific to windows - the 64-bit linux and
solaris clients work as expected (all messages are published).
It does not appear to be server dependent, I get the same
results using the pre-built Win32 Windows service, as well as
test.mosquitto.org.
What is the cause of the socket error that causes the
server to disconnect? Is there something
wrong with my sample client (http://pastebin.com/hK9vZ53H) that demonstrates the problem?
