Problematic is RB433UAH. Seem that my issue disappeared.
RB433UAH very unstable last 2 days.
1. Noticed very bad sound in SSTP VPN between RB433UAH and RB110AH.
2. Tried to downgrade RB110AH from 5.18 to 5.14
3. Lost my cert - and can't import it again (Ticket#2012071166000339)
4. Upgrade to 5.15 - same issue
5. Upgrade to 5.16 - same issue
6. Upgrade to 5.17 - imported my cert
Because of my experiments I downgraded RB433UAH from 5.18 to 5.17, to not lose cert. In 5.17 <--> 5.17 I noticed same jitter in SSTP and back to 5.18 on RB433UAH.
1. RB1100AH - 5.17
2. RB433UAH - 5.18 - very unstable(Ticket#2012071766000542) - 5-7 reboots per day with 100%CPU load. I this it depends of traffic maybe, because night it alive. Uptime was 20-39 minutes. Sent ~ 10 supout.rif

3. RB433UAH - 5.19 - very unstable.
