My YunoHost server
Hardware: VPS bought online (OVH, 2GB RAM VPS)
YunoHost version: 3.8.4.8
I have access to my server : Through SSH | through the webadmin
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no
Description of my issue
Recently my Yunohost server has been using very high amounts of RAM (oscillating between ~12% and ~7% of by 2GB RAM).
Everything seems to work well, but I had in mind much lower levels of usage before (stable at ~50%). Additionnaly, it’s quite annoying since I receive an email alert from the automatic diagnosis tool each time the RAM usage goes above 90% (can be up to 5 times a day !)
When I launch the diagnosis tool, I see the below summary
- Le système dispose encore de 227 MiB (11%) de RAM sur 1.9 GiB.
- Le système n’a aucun espace de swap. Vous devriez envisager d’ajouter au moins 512 MiB de swap pour éviter les situations où le système manque de mémoire.
- L’espace de stockage
/
(sur le périphérique/dev/sda1
) a encore 2.5 GiB (27%) espace restant (sur 9.3 GiB) !- L’espace de stockage
/home
(sur le périphérique/dev/sdb1
) a encore 33 GiB (18%) espace restant (sur 186 GiB) !- L’espace de stockage
/var
(sur le périphérique/dev/sdc1
) a encore 3.4 GiB (24%) espace restant (sur 14 GiB) !- L’espace de stockage
/var/www
(sur le périphérique/dev/sdd1
) a encore 22 GiB (79%) espace restant (sur 28 GiB) !
Questions
- Is there any way to free a bit my RAM usage without rebooting (I’m not even sure rebooting will help)
- Is there any way to stop the diagnosis tool from sending its alerts, or to change the threshold value ?
- Does anyone here face some high RAM usage since the last Yunohost update ?
- Is the absence of swap space normal ?
Thanks in advance
