IBM Worklight 6.1 - Studio waiting for "startup preview server listener to complete"

Question

I'm running Worklight 6.1 DevStudio on Mac OSX 10.8 and everything was working fine over several days of development of both adapters and a hybrid application. I rebuilt, re-deployed and ran both types of projects dozens of times with success.

The last time I tried to rebuild an adapter, it did not complete. Usually this was completing in 10sec or so. Eventually, after 10mins, I tried to stop it - eventually force quitting eclipse. Now I can not get the Worklight Development Server to start. The latest thing it is waiting on is "worklight startup preview server listener to complete". Other times it will say one of the servers will not start and do I want to wait or exit. I've had it wait up to 5 mins - I've increased the timeout. If I say exit, it hangs "forever" trying to stop the development server. I have tried:

1. Rebooting
2. Clicking "Clean Server on Next Start"
3. Forcing it down after waiting longer and longer times
4. Canceling tasks in the Progress tab in various orders etc.

Either way the best state I can get back into it is the dev studio comes up cleanly, and I can push Start, but it never completes. The Worklight Console has nothing.

The last thing in the message.log is:

[12/30/13 9:13:44:624 PST] 0000001e com.ibm.ws.logging.internal.impl.IncidentImpl I FFDC1015I: An FFDC Incident has been created: "com.ibm.wsspi.channelfw.exception.ChannelException: TCP Channel detected a possible loop on thread: Inbound Read Selector.1 com.ibm.ws.tcpchannel.internal.SocketRWChannelSelector 186" at ffdc_13.12.30_09.13.44.0.log

No idea what that means.

In the trace.log I see quite a few of these:

[12/30/13 8:50:00:281 PST] 00000015 id=
com.worklight.core.util.RssBrokerUtils 1 getBeanFactory Failed to fetch beanFactory from ProjectLocal [project ATT_WL_Banking]

Is that abnormal?

Where do I look to figure out what the development server is hung on? At this point I am out of debug ideas and considering removing the projects one by one from the workspace and re-importing or if that fails, a re-install.

Take a look at /PATH-TO-WORKSPACE/WorklightServerConfig/worklight/logs. There you will find a ffdc folder and in it the aforementioned log file. Edit the question with its contents.

I can think of two suggested approaches/solutions here:

suggestion #1:

1. In Eclipse, from the Servers view, delete the "Worklight Development Server" entry
2. Quit Eclipse. Navigate to the workspace and delete the "WorklightServerConfig" folder
3. Restart Eclipse. Re-build the project.

suggestion #2:

1. File > Switch Workspace > Other (this will simply created a new workspace with the name you choose for it)
2. Import the project(s) from the previous workspace

I'd start with 1 and continue to 2 if 1 doesn't work for you.

Answer 2

Kill java process and it would help stop the startup preview listener issue on eclipse.
