Description of problem:
used `locate`
SELinux is preventing /usr/bin/bash from 'write' accesses on the fifo_file .

*****  Plugin leaks (86.2 confidence) suggests   *****************************

If you want to ignore bash trying to write access the  fifo_file, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
Do
# grep /usr/bin/bash /var/log/audit/audit.log | audit2allow -D -M mypol
# semodule -i mypol.pp

*****  Plugin catchall (14.7 confidence) suggests   **************************

If you believe that bash should be allowed write access on the  fifo_file 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:
# grep mlocate /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
