I'm getting this error a lot with the slick forum - anyone else see this?
Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.
Additionally, a 503 Service Unavailable error was encountered while trying to use an ErrorDocument to handle the request.
-
Yes, I've been seeing that a lot in the last day or so. Usually I can just reload the page and that error goes away.
-
I saw this too. This is different than I've seen in the past. There have been times in the past when the forum completely went down for a while and then comes back alive later. Hopefully this flaky issue where some accesses fail but if you try again it will succeed will go away too.
-
This should be fixed now. Post here if you get this problem again.
-
Excellent. I wonder if you could fix the problem I'm having with msn.com web pages not loading quite often. I suspect it's Microsoft blocking chrome browser users hoping they'll switch to edge!

This issue was a problem where there were too many processes running due to this forum. Many processes weren't necessary. For the past few days we've only be using 1 process. I don't know what causes these processes to be created. The good news is that it took a long time for there to be an issue. We will have to check on the number of process every week or month to see if there are too many.
-
Processes are way up again. Happened over the weekend. We may have to come up with a different solution.
-
I just now got the error. Another refresh got me in.
-
I'm seeing this very consistently the last few days.
-
Sorry about this annoying issue
-
Still seeing these errors for at least every other page load. Several reloads will eventually get through, but it is still very annoying.
-
Unfortunately there isn't a good solution for this. The only option I can think of isn't a good one. Dump this forum, lose all data, and go with the horrible wix forum. Hence here we are.

Gemini has the suggestion below. If it doesn't help, upgrading to SMF 2.1 might help.
You could ask about the problem here

It sounds like a solvable problem.

The solution is to configure the PHP-FPM Pool (this is the most likely software they are using) to automatically manage its own processes.
The owner needs to find their PHP-FPM configuration file (it's often called www.conf or something similar inside the PHP-FPM pool.d directory).
Inside that file, they should look for these settings and change them:
Set the Process Manager to dynamic or ondemand.
The dynamic setting is the most common. It lets the server "spin up" new processes when busy and "spin down" idle processes when quiet.
This prevents the "too many processes" buildup.
The setting will look like this: pm = dynamic
Set Server Limits.
These settings tell the dynamic manager what to do. A good starting point would be:
pm.max_children = 20 (The absolute max processes allowed. 20 is a safe number, but this depends on server RAM.)
pm.start_servers = 5 (Start with 5 processes ready to go.)
pm.min_spare_servers = 2 (Always keep at least 2 processes idle and waiting.)
pm.max_spare_servers = 10 (Don't keep more than 10 idle processes waiting.)
Set a "Process Expiry." (This is the most critical fix for them)
This is the most important setting for their specific problem. It tells PHP-FPM to automatically kill and restart a process after it has handled a certain number of requests.
This is a failsafe that prevents buggy scripts or memory leaks from creating "zombie" processes that never die. This is exactly what the owner is seeing.
The setting is: pm.max_requests = 500
This means "After any single process has handled 500 web page requests, kill it and start a fresh, clean one." This automatically "cleans up" the system without any manual work.
By making these changes (and restarting the PHP-FPM service), the server will begin to manage itself correctly, and the "Service Unavailable" errors will very likely disappear permanently.

Not seeing "service unavailable" now. Using cloudflare should help too.

Make this forum read only, and switch to using reddit or similar?

Getting lots of service unavailable just now.

I am also getting lots of service unavailable just now.
