2.2 to 2.3.1 now unstable

[tongsama]

I upgraded a few sites to this. One HQ with 4 remote sites. All using IPSEC for site to site, and OPENVPN for laptop to HQ VPN.

I noticed the site to site is unstable. Have to reboot firewalls or disconnect and reconnect.

The HQ pfsense is in bad condition. The web page wont respond after 5 days or so. I need to SSH in and reset with option 11 and 16.
Today i had to do that to just get a client's VPN to connect.

Any logs i can look at for this behavior?
