Environment
Novell Access Manager 3.1 SSLVPN Server
Novell Access Manager 3.1 Support Pack 3 applied
Novell Access Manager 3.1 Support Pack 3 applied
Situation
SSLVPN Enterprise mode client running Mac OS 10.6. After successfully connecting with the Safari
browser, users get 100% utilisation on the java process for a long period of time (up to 10 mins
on occasions). Manually killing this java process seems to allow the connection to continue
without issues.
Could not duplicate issue on all machines running same OS and browser.
Resolution
Purge cache on the browser and reconnect.
Additional Information
Looking at the log files that were requested from a problem host, one could determine that the java process in use when the issue was occuring was the copyfile thread. When the SSLVPN client connects to the server, we try and backup all the temp cache files, cookies, etc when running in sandbox mode. In the above scenario, the cache file was large and the file copy process was taking up resources for a longer period of time. A defect has been opened to address this issue.
