Botnet filter crashes ASA5505

Hi,

I have a problem with my ASA5505 after enabling botnet filter my ASA reboots.

Also while booting it usualy takes around 30minutes of random cycles before loading the OS. It seems to be falling at the license check.

To fix the boot I usualy unplug the ASA for about 15minutes and then it will boot up fine.

Any ideas of what may cause this issue, or how to fix/troubleshoot it?

Thank you,

Cookie

Re: Botnet filter crashes ASA5505

Do you have the Botnet license installed?

It also states that you need a minium of 8.2 installed.

See below a useful guide:

Re: Botnet filter crashes ASA5505

Current version below, I have tried them all 8.2 and 8.3 the minute I enable botnet it crashes after 30-1hour, this firewall was rebooted 1 day again, it was stable for 98days with botnet disabled so it cannot be hardware.

Result of the command: "sh version"
