FATAL: could not create shared memory segment: No space left on device
2019-11-03 08:17:46.252 GMT [51641] DETAIL: Failed system call was shmget(key=5432005, size=56, 03600).
2019-11-03 08:17:46.252 GMT [51641] HINT: This error does not mean that you have run out of disk space. It occurs either if all available shared memory IDs have been taken, in which case you need to raise the SHMMNI parameter in your kernel, or because the system’s overall limit for shared memory has been reached.

Okay. How do I do that?
