AnyConnect Secure Mobility Client version 4.9.04053 crashes every time it connects to a gateway

[BogdanVasilescu03853]

Hello,

After the client auto-updated to 4.9.04053 it started crashing every time I connect to a VPN gateway.

This is the call stack from the dumps:

Could you please let me know if this is a known issue and if there is any workaround for it?

Thank you,

Hi Bogdan,

This would need more info than what is shared (e.g. DART logs, dump file info, client hardware/OS, if its a standalone VPN client or NAM is installed, upgrade from which version, any conflicting third party apps installed/upgraded). 

It'd be best to open a TAC case to diagnose further.

Thank you,

Hi @Dinesh Moudgil ,

Thank you for taking the time to look into this.

Could you please tell me what implies opening a TAC case? ... not sure what you mean by that.

Thank you,

Bogdan

Hi Bogdan,

You can open a Technical Assistance Center (TAC) support case with Cisco to report this issue and they can assist you with troubleshooting further:

Here is a link for your reference:
