Hi,

We're running WLS 5.1.0 (sp9) on Solaris 8 with JDK 1.2.2_07. When we shut WLS
down we get the following muxer ThreadDeath errors at the end of the shutdown:

WLS doesn't then actually shut down so we have to kill the process to get rid
of it. When we try to restart WLS we get the following error (note that I've inserted
asterisks where our IP address was displayed):

WLS is the onle process using these ports so it shouldn't hit this problem. Our
only recourse is then to reboot the server itself after which WLS starts okay.
Obviously we don't want to have to reboot the server everytime we shut down WLS.
Has anyone else encountered this problem? Any help greatly appreciated.

Thanks,

Garry
