Infinity loop of restarting when PHP thread ends with a SQLSTATE[HY000] [2002] Operation now in progress error

[7-zete-7]

What happened?

If an error occurs connecting to the database during the PHP project

SQLSTATE[HY000] [2002] Operation now in progress

, then messages like

php-28  | {"level":"info","ts":1731592008.4523456,"msg":"restarting","worker":"/app/public/index.php"}
php-28  | {"level":"info","ts":1731592008.4774933,"msg":"restarting","worker":"/app/public/index.php"}
php-28  | {"level":"info","ts":1731592008.5027137,"msg":"restarting","worker":"/app/public/index.php"}

will start to appear non-stop.

Along with this, the frankenphp_public_index_php_worker_restarts metric starts to increase rapidly.

The problem was recreated by attempting to connect using DBAL to a non-existent host from a Docker network inaccessible to the current container.

[dunglas]

Are you using version 1.3.0 ?

[7-zete-7]

Are you using version 1.3.0 ?

Yes, it's

FrankenPHP v1.3.0 PHP 8.3.13 Caddy v2.8.4 h1:q3pe0wpBj1OcHFZ3n/1nl4V4bxBrYoSoab7rL9BMYNk=

[AlliBalliBaba]

@7-zete-7 would your expected behavior be for the server to crash in this case?

There is some logic to crash the server on repeated worker failure in 1.3, but it will only trigger if script execution takes under 200ms I think.

[tomme87]

I have the same issue. Is there a workaround?
We are working with an old legacy database that sometimes is unavailable. And every time this happens, I get in a "restart loop" and need to restart the entire container to get it to work again.

[7-zete-7]

Sorry for the long reply 😅

@7-zete-7 would your expected behavior be for the server to crash in this case?

Yes, that would help. The container would restart automatically. Considering that I always have more than one FrankenPHP container running per project, it would not cause downtimes.
If, of course, there was a way to interrupt the PHP thread (and then start a new thread) for such a problem, that would be awesome.

There is some logic to crash the server on repeated worker failure in 1.3, but it will only trigger if script execution takes under 200ms I think.

200ms is too much, in my opinion. A successful launch can also work in such a time. Maybe 50ms?

Maybe there is also a way to detect that the PHP process has become, some kind of zombie?

[7-zete-7]

Perhaps it’s worth checking the number of restarts per point in time?
For example, if there were more than 5 restarts in 1 second, terminate the thread?

[withinboredom]

v1.3.2 should kill frankenphp on a restart loop, if-and-only-if the file-watcher is disabled. (for obvious reasons, if the filewatcher is enabled, it will not exit -- since you are likely doing development).

[7-zete-7]

Thanks for the information, @withinboredom!

I'll try to update to FrankenPHP v1.3.2 and try to reproduce the error.
