I'm sorry, but I believe my grep missed something: Jul 21 13:29:23 15[IKE] <109> received NO_PROPOSAL_CHOSEN error notify
What does this mean, and why is it not chosing a proposal? ________________________________ From: Turnbough, Bradley E.

I am running CentOS 6.5 (fully patched) along side of strongswan version "Linux strongSwan U5.0.4/K2.6.32-431.3.1.el6.x86_6" We upgraded a while back from a version that still used pluto to this new version (which uses charon) We've started to experience random conn drops (primarilly on sa-01 and sa-05. The only way to resolve this that I've found is to perform a 'service strongswan restart' This is not the only conn which experiences this, so I'm thinking this may be a configuration issue or a bug. The problem is, is I don't necessarily know much about ipsec. I'm hoping someone can help me out. Can anyone?
