I had applied some authorized updates to a SLES 11, SP2, (OES 11.1, PATCHLEVEL=1) running eDirectory 8.8 SP7, server and rebooted a week ago.
I didn't notice anything wrong initially and thus was living in stupid comfort! :O
I was able to get to the Novell "Welcome" web page, and I can get into iMonitor and Remote Manager, but when I try iManager, I get "Error 503 Service Unavailable".
After looking and trying various postings in the Novell forum unsuccessfully, I loaded iManager on a Linux Desktop and I am working with that, but I can't help think that is somehow related to my netstorage problem.

I am able to successfully login to netstorage and I can navigate around to folders OK.
Local users have a mapped drive and they are working OK with the nss volume.
However, then I log in as admin and select a folder and choose Properties, I get "Error 500 Server Error" and if I try it again after that I get "Error 503 Service Unavailable"
And, when anyone tries to use the other options, such as Upload or Download, nothing happens.

I verified that Apache2 is running and that tomcat6 is running.
Below is the catalina.out file for chucks-n-giggles.
