Issue NodeJS Application crashes every night

[JonathanJ]

Server operating system version

Debian 10.13

Plesk version and microupdate number

18.0.56

Hello,

I'm runing NodeJS application on a dedicated server with Plesk.
Here are the speciifications:

CPU	Intel(R) Xeon(R) E-2136 CPU @ 3.30GHz (12 core(s))
Version	Plesk Obsidian v18.0.56_build1800231106.15 os_Debian 10.0
OS	Debian 10.13

I have the same problem on several servers.
Its around 1am sonde apps going error 500 without details.
The websites are going UP as soon as i restard manuelly Apache webserver in Plesk Services Management.

As a workaround i tried to setup a cronjob restarting apache several times in the night but this changes nothing.
I searched lot of forum topics but can't find a solution and don't know where to search further.

Please help.
I'm disposed to give you any specific log you need.

Thanks in advance

Did you check your /var/log/syslog (/messages) and the general Apache log file /var/log/apache2/error_log for details?

I don't think there is so much things, please find what i can find related to Phusion Passenger:

Does these logs gives you some information ?
Do you think this is related ?

Thanks in advance

The log segment only shows that the process is stopped. As it happens at midnight, normally there are only two typical reasons: One is a cron job that is doing it, the other is a backup job that stops services before doing a backup.
