vpnagentd crashing often - segfault libstdc++.so.6.0.16 (Linux)

[cwall2015]

vpnagentd crashing frequently - sometimes 5x in 30mins.

Several of us at our company are experiencing, and IT is unable to solve.  Restarting vpnagentd then reconnecting VPN works, but this is not a productive work environment.  Sometimes networking is down completely (requires clearing resolv.conf, iptables --flush, etc).

Assistance is greatly appreciated.

What additional information can I provide?

I'm having a perhaps similar - if not the same - issue with 64-bit Mobility Client Version 3.1.07021 wherein suddenly it drops connection and then can't find the VPN service.  At first I had to restart the whole Ubuntu workstation but now I've tracked it down to having to service vpnagentd start as it seems the daemon is crashing and needs to be restarted before the client can function.

Here's my details.

Can Cisco tech support help us?  There's at least 3 persons in my company who are experiencing this issue.

Thanks.

Hello everybody I think I know why there is no help from Cisco on this situation and it just might be how great Openconnect works!  After upgrading to Ubuntu Desktop 15.04 (64bit) from 14.10 things got worse with AnyConnect 3.107something-or-other completely filling my upload pipe with who knows what every single second of its' connected time.

I checked to see that 3.108something-or-other had just recently been released and thought maybe that's what I needed to do so I tried it and no change - relentless sending of who knows what kind of data, anyway.

Well that is utterly unusable so out of frustration I did some digging around and found out how to install and then plug Openconnect into my network manager and it's working just brilliantly!

I would like to sincerely thank Cisco at this time for completely ignoring our issues so that I could be led to what is, in my opinion, a superior solution even if AnyConnect WAS working properly!

Well done fellas!

I am now experiencing vpnagentd crashes once or twice per day.  This is new for this particular installation, having been long-term stable.
