Hi. I'm running autofs 5.1.4 on Fedora 27. I've come to discover that automount is holding a lot of file descriptors. Over 5K of them. About half of these are in half-open TCP sockets (to NFS server port 2049 in a small number of NFS servers) and the other half are UDP sockets. $ ps -ef | grep automount root 2075 1 0 May04 ? 00:00:40 /usr/sbin/automount --foreground --dont-check-daemon # lsof -n -p 2075 | grep CLOSE_WAIT | wc -l 2711 And the UDP sockets in the form of: automount 2075 root 5404u IPv4 18768127 0t0 UDP *:37151 # lsof -n -p 2075 | grep UDP\ \\*: | wc -l 2664 As you can see, just those two together amount to over 5000 open file- descriptors. Any ideas or thoughts? Cheers, b.
