Hi,

I am getting this error when trying to start kerio from terminal: Cannot start remote admin server on port 44337: TCPIP not available or port already in use

Kerio is on a Mac Mini running 10.8.4 and connect 7.4.3, the server runs ok for a while and then just stops no access to webmail, admin or any mailbox the logs show no activity but in control panel it shows connect as running? Try to restart it using terminal and the above message appears. Restarting the server is the only way to get it up and running again. There is no firewall and port 44337 is not blocked any ideas?

Thanks

Hi, Stephen and welcome to the forums!

When the service doesn't start, you need to take a look at the services currently running on your system, so you will need to open a Terminal window on the server itself and use the following command:

lsof -i -P | grep -i "listen" | grep 44337

This will only reveal the correct information when the service no longer runs or restarts.

If you need advice, please post here and let us see the output so that we can try to advise further.

Hi

When I type the command in 'lsof -i -P | grep -i "listen" | grep 44337' it just gives me a new line in terminal.

Thanks

Steve

try running it as root,

sudo lsof -i -P | grep -i "listen"


if you run the command as yourself, you'll only see the processes run as your user. Running the command as root will show all users' processes which bound to a ports.

looks like kerio connect is still running. When you say you tried to restart it using terminal, what steps did you take?

You could also try stopping the mail server via the System Preferences > Kerio Connect Monitor panel.

If that fails, try:

sudo /usr/local/kerio/mailserver/KerioMailServer stop


Then:

sudo /usr/local/kerio/mailserver/KerioMailServer start

Hi Dominic

I tried sudo /usr/local/kerio/mailserver/KerioMailServer restart which gives me the above error, stop does work but then it wont start and gives the same error. The machine then has to be restarted to get mail back up and running again.

Thanks

a couple things to keep in mind.

1, it can take a surprising long time for the mail server to quit as it tries to close existing connections, etc.. Yu could try killing it ( most definitely a last resort ) via killall mailserver or just kill [ process id ]

2, there is are launchd items, configured to automatically start the mailserver process ( on first boot, crash, etc. ), which may be interfering. You could try unloading these first, /Library/LaunchDaemons/com.kerio.watchkms.plist and com.kerio.mailserver.plist, and then manually restart.

But rather than restart kerio connect or reboot... Back to your original question/post. Perhaps its http/httpd service that is getting hung up, not the mail server in general? It might be worth opening a ticket with Kerio support to figure out why it's locking up for you, instead of figuring out how to manually restart it, no?

Thank you Dominic, that is actually what I was going to recommend! Smile
