[vpsFree.cz: community-list] nginx padá

Ne že bych znal nginx nějak dobře, ale přijde mi divné, že by sám od
sebe bez vnějšího povelu najednou 23:40 restartoval. A jinak nechápu
proč by dělal znovu listen. Klidně to může být nějaký posthook na
certbotu (ale ten to snad dělá jenom když je nový certifikát, ne?).
Koukni taky na log CRONu nebo také máš systemd, tak ten má taky nějaké
naplánované úlohy.
Přijde mi to, jak kdyby se pustil nějaký restart, starý proces se
nestihl z nějakého důvodu ukončit a už se startoval nový. Je nad tímhle
záznamem ještě něco dalšího velmi blízko (< 2min) před tímto časem?
Neboli - prošel bych všechny systémové logy a podíval se co se dělo
okolo času 23:40 a pokusil se zjistit příčinu restart nginx.
