I've got this warning log early by the morning on my php saying that it couldn't allocate memory when I was trying to connect to my database.
This is the log:
[26-May-2017 08:41:12 UTC] PHP Warning: include(../../../System/Functions/LocalDB.php): failed to open stream: Cannot allocate memory in /LocalSettings.php on line 4
The only thing in that line is an include to the LocalDB.php
file.
It was the first time it happened and this file is executed several times a day and the server is hosted on a Jelastic environment.
This memory allocation error may be because the server ran out of memory?
EDIT
Also, here is the monitor graph of the server on the time of the error, everything looks normal.
