Hi

I used CustomBuild 2.0 to update DA to 1.62.0. When loading sites on the VPS server, the browser intermittently displays errors:

Service Unavailable
The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later.

This was not happening immediately prior to the update.

I am running on CentOS 8 and Apache, php1_release = 7.4, php2_release = 8.0. Most sites are using php 7.4.

From the command prompt, when I run the top command, the CPU seems to be mostly idle. I do not believe it should be a capacity issue.

Are there any checks I can run to find out what the cause is?

Regards
 
I used the above help file to run pre-release. However, afterwards, when I check the version it still shows me this:

/usr/local/directadmin/directadmin c | grep -i 'version='
version=1.62.0
show_php_version=1

So far since running the command in the "Installing a pre-release version of DirectAdmin" help page above, I have not had the Service Unavailable error. Is there a known issue with DA 1.62.0?

The version number should stay the same, so, it's normal.

Regarding the issue - you likely have some other services not starting, 1.62.0 has a bug that it restarts PHP-FPM too, in case other services are having trouble. I'd suggest checking the other services, as they likely have a problem (for example, bind/named not starting).
 
Thanks. I did not check the services prior to running the pre-release, so not sure about that. They are all running now when I check the Service Monitor, with the exception of vm-pop3d which I manually stopped a while ago, since my email is all off-server.

smtalk in version 1.62.0 (fixes many previous bugs, thank you) any service that is available in services DirectAdmin with status ON also with OFF (if DirectAdmin dont was reloaded)
like lfd / spamd, clamd, freshclam, proftpd etc and it is disabled in os that will cause php (fpm) reloading every minute.

Also as there is CSF on the server and you put it in testing mode which will disable ldf, it also causes reloading of all php (fpm) versions.
If there are many versions of php (fpm) on the one server and some of them won't work/responding, it also causes reloading of every version of php (fpm).

We report it and this in the prelease beta version, corrects it. https://directadmin.com/features.php?id=2985
It was quite significant and a new stable version should be released soon, because many people will be looking for php (fpm) problems elsewhere, like: 503
Connection reset by peer: [client xxxxxxx:15552] AH01075: Error dispatching request to : ,
or
AH01067: Failed to read FastCGI header, referer:

Upgrading to the beta when managing many servers with DA in this case on productions is risky.
+1 for the quick release of a stable version with this patch.
