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 allocates memory according to RLIMIT_NOFILE, so decrease RLIMIT_NOFILE to 4k to keep sync with sysvinit After applying the patch, the memory cost is the same with sysvinit rpcuser 340 0.0 1.0 3212 2588 ?
