rails4 + puma + nginx // random puma crashes


Vote count:

0




I have a bunch of rails app running under nginx via puma web server. It works pretty well, fast and stuff.


But, I have some puma processes crashing once in a while without any particular obvious reasons. From this getting some 502 errors, need to cap deploy:start. It occurs more than just sometimes, without traffic peak, without clear reasons.


As I understand it is specific for each apps, at the same time I lack of knowledge about how to understand this can happen, and I'd like to have some tips about where to start investigating this kind of stuff (nginx log, rails logs, mysql logs… ? or absolutely something else ?)


Thanks for sharing some experience
