From 6d61cd2bdc9e326eaa59082b5dd7423e522b96d3 Mon Sep 17 00:00:00 2001 From: Hongxu Jia Date: Tue, 20 Aug 2019 01:45:18 -0400 Subject: nfs-utils: decrease RLIMIT_NOFILE to 4k for systemd On systemd, it set RLIMIT_NOFILE to 512k, since do_testimage for core-image-sato-sdk has memory limitation (256Mib) which caused rpc.statd failed with out of memory. [ 531.306146] Out of memory: Kill process 193 (rpc.statd) score 200 or sacrifice child The rpc.statd and rpc.mountd allocates memory according to RLIMIT_NOFILE, so decrease it to 4k to keep sync with sysvinit After applying the patch, the memory cost is the same with sysvinit: root@qemux86-64:~# systemctl status nfs-statd * nfs-statd.service - NFS status monitor for NFSv2/3 locking.
