accept error(Error: Too many open files) #588

dwrobel commented 3 years ago

I installed the 1.4rc1 version on five x86_64 machines and started to compile linux kernel sources using: make defconfig; make -j all

On the localhost machine I've observed Error: Too many open files):

Looks like it reached the limit:

$ sudo -u icecc ulimit -n
1024
$ sudo lsof -p 515279 | wc -l
1052

The /var/run/icecc/iceccd.socket seemed to be opened too many times:
