ASDM takes long time to load after updating to 7.18(1.152)

[Daniel LRA]

After updating the ASDM to version 7.18(1.152) (OpenJRE) on my 5506-X ASAs and installing the new launcher on my PC (v.1.9(5)) I noticed that it takes a long time until the ASDM is fully opened. I enter the IP, user and password, login and then the ASDM is displaying "Checking the launcher version compatibility... done" for several minutes.

I found out that the network traffic on those firewalls goes up while trying to connect, which makes me believe that the ASA is sending the whole ASDM image (just a guess) to the client for some reason. Maybe because of the new support for signed images? Waiting several minutes until I can actually do something is a bit too long, especially on sites with a weak internet connection. Is there any fix to this? It's one reason that keeps me from updating more appliances at the moment.

Problems with ASDM are quiet frequent also for me. Downgrading from 7.19 to 7.18.1.152 reduced (for me) the delay from 90 seconds to 60. To be honest this problem is a "glitch" but when you are used to load the GUI in few seconds ... it can be a little frustrating.

Currently experiencing extremely long load times with 9.16.4.14 and ASDM 7.19.1.90 (asdm-openjre-7191-90.bin)

Also stuck on "checking launcher version compatibility ...done"

It appears there might be a fix in 7.20: CSCwd58653 : Bug Search Tool (cisco.com)

It looks like 7.20 might not be available for public release yet. The latest ASDM available is 7.19.1.90.

If anyone has a TAC case and can get an early release, could you confirm in this thread if it worked for ya?

Seems like the problem is fixed. I just updated one appliance to ASDM 7.18.1.160, which installed the ASDM launcher v1.9(7) on my client. With this launcher version I can connect much faster, even on ASAs still running 7.18.1.152.
