I get blank pages, and this little gem when I attempt to read private messages. | Code: | phpBB : Critical Error
Could not connect to the database |
Blessed be!

No blank pages yet today (lots last evening), but I just had the private message issue. I clicked reload four times, and it finally caught.
BB!

Unless the forums software is able to handle 'wandering' https-sessions and alike correct you probably have to - had similar issues with one of my (3 nodes)-clusters. Currently they're working with 30 min. timers and noone complained during the last 3 months. Balancing on https-sessionid + least connections for http.
Sessions are more or less split evenly across the servers.

I don't split single connections over multiple servers, and keepalive is turned off, so there shouldn't be any SSL keying issues regardless. My work deployment of IPVS has many TiB of traffic driven over HTTPS without issues. |

I had to login ~20 times to post a reply in a thread. It will be amusing to see how many times I need to login to post this one ....

sid = http(s)-sessionid?
_very_ wild guess: How does the LB check the backend servers if they're up or not? Hopefully not (solely) by icmp ping but via 'tcpping'-checks on the webserver ports (i'd not mention it if i wouldn't have done the same stupid error once)

I think it's phpbb's sessionid... it's a ?sid= tacked at the end - it has showed uip occasionally for the last year or so... it was always coming up, and always different today when trying to log in.

It is.
Some modifications have been put in place to attempt to fix the problem, but there may be further steps required to fix it completely. |

| Interesting, when you got logged out, your browser hit the same page twice in one second, then grabbed some associated files. Judging by page sizes, it seems like the first hit you were still logged in, then the second you weren't. |
