Question Can anyone let me know what this Complete Memory Dump reads when I get a blue screen?

[Tennis987]

Been having Issues with my Dell Precision 5540 laptop blue screening once a day while on VPN. Did a complete memory dump and opening it in WinDbg but don't know how to read it. I see that the issue is acsock64+549c which is VPN. I have Cisco AnyConnect 4.10 but i reinstalled VPN 3 times and I am still having issues. Bios Version 1.19. Cleared all old VPN files too. Not sure where to go from here. If there is any additional info you need let me know.

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, refurbished, used)?

Disk drives: make, model, capacity, how full?

Also look in Reliability History/Monitor and Event Viewer.

Either one or both tools may provide more information and details from just before or at the time of the blue screens.

Have you asked you IT department about this. The anyconnect software is part of cisco licensed vpn offering. It is very hard to get any support without a support contract. I do not know if you can download patches for the anyconnect client without a cisco account.

In addition cisco has end of life all the anyconnect software. What they really did was just rename is secure client when 5.0 came out. I have not read the details of what the last date really is you can get software updates or support from cisco. It was a year or two that I saw the announcement.

Hard to say it is a crash inside the vpn software itself and even if cisco had a way to look stuff up it is all locked behind a paywall.
