All services are alive all the time and both contexts are alive all the time.
when user tries to access LBR2:80's URL it works all the time. but when user tries to access LBR1:80's url then it works sometimes and some times it doesn't work.
could you advise what the issue could be?

Answer 1

When the SYN comes in the CSS will first check for the srcip in the sticky database and if it finds a match will forward to the stuck server. If the source ip is not in the sticky database the request will be load balanced using weightedrr and a server selected. That sticky server will then be added to the sticky database.
If the sticky-srcip is used between 2 content rule, it will use separate sticky table.
You may need to take packet capture to understand what is really failing along with
a following outputs :
sh flow
sh rule Ow1 LBR1:80 ser
