** Description changed:
After a few days of use openconnect is starting to consume huge amounts
of memory (3,7GB).
openconnect is used through network manager and this is the ps output:
USER PID %CPU %MEM SZ RSS STIME TIME COMMAND
nm-open+ 2289 1.3 48.0 - 3885440 Jul14 00:33:25 /usr/sbin/openconnect
--servercert ************************************************** --syslog
--cookie-on-stdin --script
/usr/lib/NetworkManager/nm-openconnect-service-openconnect-helper --interface
vpn0 host.name:443
It seems like a memory leak or something similar.
The error can be reproduced consistently and appears to be happening after
2-5 days.
It does not seem to be a constantly increasing leak as I have monitored the
process and memory usage was normal for a few days and after that when I
started working in the morning I realized the high memory usage.
I have even seen OOMs in the kernel log:

The only way I could find to fix this is disconnect and reconnect.
This is a serious issue and prevents me from working.
I have been using openconnect in the last 4,5 years and I havent
experienced this before, but after upgrading to 15.04.
