ASDM crashes

I am having repeated issues with ASDM crashing while loading. The ASDM launches successfully, show me the screen where it is discoverin device version... gets to 17% and the crashes. No error message, no windows error screen, just the program closes. Any ideas? I've tried de-installing / isntalling java from SE6 update 1 - 7 individually with no success. ASDM launches is version 1.5(22) connecting to an ASA 5520.


Re: ASDM crashes

Try uninstalling every version of Java visible in the control panel. Empty recycle bin. Empty prefetch files (C:\Windows\Prefetch) and then reboot the computer to dump RAM.

Install Java. Try again. See what happens.

Re: ASDM crashes

Hi Thomas,

What versions of ASA and ASDM software are you using?

Also, take a look at the output that gets written to the Java console when you are trying to launch ASDM. This may give you some insight into where the load is failing.

Re: ASDM crashes


The firewall is ASA 5520 version 8.0(2)

I've tried a variety of the ASDM varieties - v1.5(22) v1.5(24) v1.5(30) and all fail at the same time.

Turned on logging and java console. The last line the java console shows is invoking sgz loader... and then closes. Actual program never gets above 17%.

No error, no log to be found. ASDM works great on my laptop - just not the desktop.

Been down the uninstall java path - no help.
