I've updated 2 VM's so far but both have problems to update the iManager plugins after the install of Update4 and rebooting. iManager always seems to hang during the uninstall phase of updating a plugin. For example, iManager spawns an uninstall process like:
java -Djava.awt.headless=true -jar /var/opt/novell/iManager/nps/UninstallerData/Uninstall_SNMPConfiguration/uninstaller.jar -i silent
But the process just stays there and never makes progress. If I kill this process iManager continues with the install phase of the plugin and successfully installs the plugin. Then iManager hangs again with the next update process.
Otherwise Update4 works fine here on these VM's.
