zmconfigd startup: Error creating listener socket, Address already in use

[gunthor]

hi,

I'm playing since 2 days to startup right a clean zimbra installation. It is working with emails, but zmconfigd is not working, it fails to start up and try to start in a minute loop.

this is the log:

(version: Release 7.1.1_GA_3196.UBUNTU10_64 UBUNTU10_64 FOSS edition.)
=========================

zmconfigd WARNING [28235-rewrites] Rewrote: /opt/zimbra/conf/salocal.cf with mode 440 (0.03 sec)
zmconfigd WARNING [28235-MainThread] All rewrite threads completed in 2.70 sec
zmconfigd WARNING [28235-MainThread] All restarts completed in 0.00 sec
zmconfigd CRITICAL [28235-MainThread] Error creating listener socket on port 7171: (98, 'Address already in use')
zmconfigd ERROR [28235-MainThread] Service unavailable ((111, 'Connection refused'))
zmconfigd CRITICAL [28235-MainThread] Can't create listener socket: (98, 'Address already in use')
zmconfigd CRITICAL [28235-MainThread] zmconfigd: shutting down
Failed to start

=========================

Normally the error "Address already in use" comes because the port is locked for a short time, i tried different ports and checked double with netstats -anp , but the port should have been free, i didn't find it open. allow_reuse_address should also be some kind of workaround for this.


on /opt/zimbra/libexec/zmconfigd:104 zimbra want to build the server with the socket:

=========================
def requestListener():

listener_params = ("localhost",int(state.State.mState.localconfig["zmmtaconfig_listen_port"]))
try:
server = listener.ThreadedStreamServer(listener_params, listener.ThreadedRequestHandler)
except socket.error, e:
Log.logMsg (1, "Error creating listener socket on port %s: %s" % (state.State.mState.localconfig["zmmtaconfig_listen_port"],str(e)))
if contactService("STATUS"):
Log.logMsg (0, "Can't create listener socket: %s" % str(e))
else:
Log.logMsg (0, "zmconfigd service already running, exiting")

=========================

The Server itself is contained in:
on /opt/zimbra/zimbramon/pylibs/listener.py

=========================

class ThreadedStreamServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):
allow_reuse_address = True

def shutdown(self):
Log.logMsg(5, "Removing socket %s" % self.server_address)

=========================

I tried to run the build a testing file to test listener.py, and there it didn't made the error ( I run it under the user zimbra):

test.py
=========================
import socket
import SocketServer

class ThreadedRequestHandler(SocketServer.BaseRequestHan dler):

def handle(self):
pass

class ThreadedStreamServer(SocketServer.ThreadingMixIn, SocketServer.TCPServer):
allow_reuse_address = True

if __name__ == "__main__":
# Port 0 means to select an arbitrary unused port

try:
listener_params = ("localhost",7171)
server = ThreadedStreamServer(listener_params, ThreadedRequestHandler)
except socket.error, e:
print "Error creating listener socket on port 7171: %s" % str(e)
if contactService("STATUS"):
print "Can't create listener socket: %s" % str(e)
else:
print "zmconfigd service already running, exiting"

#HOST, PORT = "localhost", 0

#server = ThreadedTCPServer((HOST, PORT), ThreadedTCPRequestHandler)
ip, port = server.server_address


server.shutdown()
=========================

Has someone an idea where I stuck? How to debug it?

I'm grateful for any help!

thank you,

(the issues was discussed here:

zmconfigd stopped - how to proceed?
, with a backup it started to work again)

...deactivating the IPv6 Adresses solved this issue.
