linux - Kubernetes can't start due to too many open files in system -


i trying create bunch of pods, services , deployment using kubernetes, keep hitting following errors when run kubectl describe command.

for "pod" runcontainererror: "runcontainer: api error (500): cannot start container bbdb58770a848733bf7130b1b230d809fcec3062b2b16748c5e4a8b12cc0533a: [8] system error: many open files in system\n"

i have terminated pods , try restarting machine, doesn't solve issue. not linux expert, wondering how shall find open files , close them?

you can confirm process hogging file descriptors running:

lsof | awk '{print $2}' | sort | uniq -c | sort -n

that give sorted list of open fd counts pid of process. can each process w/

ps -p <pid>

if main hogs docker/kubernetes, recommend following along on issue caesarxuchao referenced.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
