Initial near run use too many open files #1942

Closed ailisp closed 4 years ago

ailisp commented 4 years ago

it uses more than 1024, linux system default, recently and we have to raise ulimit. It shouldn't this many

I can't run several tests at the same time in clion because of this problem. I should run them separately.

before i fix it, you can update system ulimit in /etc/security/limits.conf. I cannot even run single test :)

It has 1802 open files, of them 1647 are something like:

near    6237   bo 1783r      REG                0,4         0  217208 /proc/6237/task/6796/stat

by print lsof on each step i found ClientActor::new opens ~1700 files. will further break down investigate tomorrow
