At this point integration server is stuck. Not sure why this is happening recently. I went through the logs and found there was an issue with threads earlier

Have you tried disabling the non-webMethods packages (you can do this by modifying the manifest.v3 file under each package physical directory) and starting?
At minimum, disable the non Wm* packages. At max, disable everything but make sure you leave Default, WmPublic, and WmRoot enabled.
Once the server starts (if it does) you can selectively enable packages through the Administrator and see which one chokes.
This is an easy test to identify if a particular package or circular dependency in packages is causing a problem.
Try bringing up the IS in safe mode…“server.bat -safeboot” and this will enable only the WmRoot package. In my expereince i saw this happening due to a custom package/code issue so you might want to investigate in that direction. Also, this might be of some help…
