I was reading another post that suggested running the K2 Host Server in console mode and I saw an error message that popped up:

;Error Invoking 'StartHostServer' : bind() Failed. Error code: 10048
;Stopped Hosting Server Runtime

I have seen this error in the Console mode when the K2 Host Server is already running in Service mode.  Can you confirm that the service is not already running in the Windows Service Applet?

Also, have you tried enabling logging within the K2 (to log to a File and/or Event Log) and then restart the K2 Blackpearl Service to see if the service is encountering the same error as when in console mode.

1.) Yes the machine has been restarted.

2.) I don't see any errors in the log file that the host creates.   There are some Debugs and Infos in the log, but no errors or warnings.  Is this the correct setting for logging to a file:

<LogLocation Name="FileExtension" Active="True" LogLevel="All" />

 I have also tried repairing the installation, but that didn't seem to help.

I have attached the file.

What else is running on this machine?  I think the error in the log points to a bind failure where we were unable to start listening on port 5252 because something else already was.

 Run this command on the server and see what it looks like

netstat -a

you can also just pipe it to a log file for easier reading

netstat -a>C:
etstat.log

Chris,

 Thanks for the reply.  There is nothing in the netstat output that indicates something is running on 5252.

Ugh. I just saw a windows firewall message on the server.  I disabled the Windows Firewall (which I had sworn I had done previously) and I think it has gotten past the bind error.  I am still seeing error messages with my smart objects, however, since my dev. license expired today, I probably will not get to work on this until I can get a new license key.

So I changed the port that the host server was running on and that seemed to help my problem on the workspace page, however, after I create a Smart object in VS2005,  I get an error stating  "Cannot connect to the Host Server.  Please make sure the hostserver is running and that you can connect to it.

 Invalid Packet Header Received!!!!"

 This error is on the design page of SmartObject1.sodx.

Did you really solve your problem dealing with port 5252 by changing the K2HostServer listening port? (which is 5555) I would have guessed you changed the K2Server port instead. But Blackpearl keeps on surprising me :-)

Thanks Chris that seemed to fix my SmartObject error.

 Nicolas:  I changed both the Host Service Port and the Workflow Service Port in the configuration manager. 

Please have a look in the environment library and confirm that the connection settings are configured correctly with server and port names. By default the Workflow server run on port 5252 and host server (including SO Service) run on 5555. My best guess would be that the SmartObject server connection string is incorrect.

You mentioned a couple of posts back that your license had expired.  Have you recieved and applied a new one yet?

I have face this issue as well, after I upgraded to SP1. Any one have idea to resolve it?

Eikden,

 What error message are you seeing?

Hi,

 I'm getting exactly the same error while trying to deploy my workflow on the K2 BP server. I triggered a simple netstat -a and the 5252 port doesn't seem to be bound to any process...

 
My license key expired last night (development purposes) and I had to reconfigure/reboot the server to update the license key and now after installing the process, I'm able to get the management console within the workspace (port 5555) but unable to connect to the 5252.

PS : I just tried to replace strictly all "5252"  occurences by "5555" in all connection strings (workflow server, so server, etc.) workflow management server, etc... In production AND developpment environments... but it still says it can't connect to the 5252 port while deploying... Any idea ?

 
Thanks in advance if you have any idea.

Cheers
