Issue while stopping server.

Hi,

    I have installed clm 6.0.6 ifix009  version (as per websphere liberty procedure).

Deleted existing lqe.war, rm.war, qm.war, ccm.war, relm.war files from C:\IBM\JazzTeamServer\server\liberty\servers\clm\apps directory and C:\IBM\JazzTeamServer\server\liberty\clmServerTemplate\apps directory.

Replaced with new files.

But now am not able to stop or start the server.

In the logs, stop.log  shows below exception:

java.io.FileNotFoundException: C:\IBM\JazzTeamServer\server\liberty\servers\clm\workarea\.sLock (Access is denied.)

Can anyone suggest whats the issue and how to resolve it.

Thanks in advance.
