Tail: stdout: No such file or directory

[ioiioi]

I am troubleshooting the webUI problem on pfsense 2.3. when execute the following command on shell:

tail -f /var/log/system.log | grep php-fpm

Binary file (standard input) matches
tail: stdout: No such file or directory

I definitely confirm that the system.log is there. so, how to fix it?

clog -f not tail -f
