Failed To Memlock Pages Error 12
Hello list, I recently want to enable LockPagesInMainMemory in our MySQL Cluster, then I put it like this in config.ini : [ndbd default] LockPagesInMainMemory=1 Everything seems to be okay, until I realize that there¹s warning in the log file which says ³Cannot allocate Memory² [ndbd] WARNING -- Failed to memlock pages, error: 12 (Cannot allocate memory) We use latest NDB binary (ndb-7.1.5), I also has reconfigure the memlock limit: $ ulimit -a core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 20 file size (blocks, -f) unlimited pending signals (-i) 16382 max locked memory (kbytes, -l) unlimited max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) unlimited virtual memory (kbytes, -v) unlimited file locks (-x) unlimited Please anyone if have suggestion what I¹m supposed to do.
