Description Daniel Stiner 2017-09-13 18:56:46 UTC 
Description of problem:
Install and connect to postgres 9.6.4. Postgres crashes with error "GotoBLAS : Can't open shared memory. Terminated." 
Postgres is crashing with "GotoBLAS : Can't open shared memory. Terminated."

SELinux is preventing postgres from unix_read, unix_write access on the shared memory Unknown.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that postgres should be allowed unix_read unix_write access on the Unknown shm by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'postgres' --raw | audit2allow -M my-postgres
# semodule -X 300 -i my-postgres.pp

Description of problem:
I got a notification from SELinux after I woke my laptop from sleep, though that may be coincidence.  Other than that I'm not sure what caused it.
