Hi,
I’m getting the following crash during startup. It seems strongswan is setting
a reqid.
Commit r363430 is on if_bridge. The IPSec interfaces are not bridged at all, so
I’m clueless to why this crash relates to this commit. The only commonality is
that the crash is Epoch related and the commit as well.
