Number of CHILD_SA for a single connection grows over time
strongSwan 5.5.1 on Ubuntu x86_64 successfully establishes a connection to an OpenWrt 14.07 router running strongSwan 5.x, but over time the number of CHILD_SA for a connection grows (roughly 11 additional CHILD_SA per day).
Attachments (all from the road warrior uni-user-dring1):
syslog-manyconnections.txt.xz: complete syslog since the last restart of strongswan
ipsec-statusall-manyconnections-failednetwork.txt: when the router didn't respond anymore
ipsec-statusall-afterrouterreboot-1.txt: directly after the router had been rebooted
ipsec-statusall-afterrouterreboot-2.txt: short while after ipsec-statusall-afterrouterreboot-1.txt, strongswan on the router stopped responding to requests for a new connection again (but old connections from other clients were still alive)
I have another "ipsec statusall" output from a previous run where I had 22 CHILD_SA for the same tunnel, but I didn't upload it here to avoid mixing logs from two different runs.
