JAVA memory heap size and ASDM or IDM

fsebera — Sun, 10 Mar 2019 11:55:03 GMT

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

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 This JAVA down grade fixed my IPS management issue but now security folks have issues with my old outdated JAVA version.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

Re: JAVA memory heap size and ASDM or IDM

a.moerman — Tue, 06 Apr 2010 05:10:01 GMT

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.

java -Xms -Xmx

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.

"C:\Program Files (x86)\Java\jre6\bin\javaw.exe" -Xms256m -Xmx512m -Dsun.swing.enableImprovedDragGesture=true -classpath lzma.jar;jploader.jar;asdm-launcher.jar;retroweaver-rt-2.0.jar com.cisco.launcher.Launcher

Thanks,

Updated my Java and ran into this problem. You think Cisco would change the target to meet the minimum memory requirements for the most memory hungry application using the ASDM-IDM launcher.

Can the original poster please mark this as "fixed" please?

I'm running ASDM Version 5.2(5) on Windows 2003 5.2. Java Version is 1.6.0_20.

I solved the Java memory heap size problem by modifying the asdm-launcher.config file in the same directory as asdm-launcher,exe. I changed two vmparam entries, the -Xms and -Xmx to 256m and 512m respectively.

Hello fsebera,

This is likely due to, "CSCtf21045: With Java 6, Update 18, IDM does not load due to heap size check." This issue is resolved in ASDM 6.3(4) and 6.3(4)53, which are currently available on cisco.com.

Thank you,

I have a similar issue, but just when selecting the IPS button under configuration.

I'm running IE7 and Java 1.6.0_21 on XP, with ASDM v5.2(5) on ASA 7.2(5) .

ADSM runs fine, just the IPS section.

****EDIT:

I just cracked this. It was slightly different for mine, as the Java Control panel change or the shortcut edit didn't work.

On mine, I had to do the following:

- Right click "Cisco ASDM Launcher" > Properties

- Click "Find Target"

- opens ASDM target directory

- disabled "asdm-launcher.config" file from read-only

- edit the file, changing the 2 params for Xms and Xmx to 256 & 512

- save, close and revert to read-only

- restart ASDM and my IPS section works
