We are using a package for running SSH commands from the IS. Problem is, the execCommand service in this package run fine in one webMethods 10.15 IS but not running in another 10.15 IS, it keeps on running indefinitely without completing. I have to disconnect the IS from designer to abort the running service. This is the case even when the SSH host is given as the localhost. The fix level is identical in both these nodes. It doesn't look like this is an issue with the package alone. 

I raised a ticket to IBM but turns out this is an open source package(https://github.com/ibm-wm-transition/webmethods-integrationserver-wxssh/tree/master) and they won't support issues related to this. 

Has anyone faced this issue? 

The fact that its running in one instance but not the other would indicate that the package itself is fine. It could be a connectivity issue. I would recommend that you first try to do this from the host of the instance where its not work i.e. try the command line SSH instance to see if the connectivity is fine. 

In addition, it might help to check the logs and the service usage. Those can indicate where exactly is the execution stuck. A thread dump can also provide valuable insights about the same, but only if you know how to analyze threads dumps. Service Usage should show a service in running state during the time you are locked out.
