When I try to load ASDM or IDM with either IE or Firefox, I receive the following error
ERROR: Current JAVA memory heap size is less than 256MB.
You must increase memory size before running IDM.
Click on help for more information.
Instruction provided by Cisco refer to JAVA 1.4.2 and 1.5
We run Java verison 6 and the instructions - although similar - do not work for JAVA version 6.
I did enter the -Xmx256m in the Java Runtime Parameters field but it still failed.
I also rebooted the PC just for fun.
My exact JAVA version:
JAVA 6 update 18 build 1.6.0_18-b07
Any help would be wonderful!!!!
Tks
Frank

Hi ,
Please do check your Operating System like 32bit or 64bit, please download the JRE based on your operating system and it should fix your problem immediately, please refer the below link for downloading latest compataible JRE for your OS.

Tks
I removed JAVA 6 from my MS XP OS and installed JAVA 5. This JAVA down grade fixed my IPS management issue but now security folks have issues with my old outdated JAVA version. Win some, lose some.

The only way I could get this thing to operate was to downgrade to JAVA 5.
If there is another way, no one is talking.
Good luck

If you didn't already, try setting it under both the user and system runtime properties...
You could also try setting it to 512, or try setting the initial heap size to 256.

yep this really sucks ... and you know what? it's not the first time I've had this issue ... now that Ellison owns Sun, let fun really begin!
Downgraded from SE 6 update 19 to JRE SE 6 update 7 and it works now. Finding SE 6 update 7 wasn't easy. To to save anyone else this grief:

Hi There,
Try modifying the shortcut that launches ASDM. I found mine runs javaw but sets the min mem to 64 and max to 256. I changed these to min 256 and max 512 and that fixed the issue. Im running the latest Java.
Rgds,
DJ
