Hi,

vfs.file.exists returns '0' for socket files until other files checks successfully. Could you please check it?

$ ls -l /run/
total 56
rw-rr- 1 root root 5 Nov 5 20:26 acpid.pid
srw-rw-rw- 1 root root 0 Nov 5 20:26 acpid.socket

$ zabbix_agent -t vfs.file.exists[/run/acpid.socket]
vfs.file.exists[/run/acpid.socket] [u|0]

$ zabbix_agent -t vfs.file.exists[/run/acpid.pid]
vfs.file.exists[/run/acpid.pid] [u|1]

'stat' command returns result for the socket file too.

$ stat /run/acpid.socket
File: `/run/acpid.socket'

What is going on with all this things?

Thanks in advance.
