I started /usr/bin/virtiofsd --socket-path=/tmp/tv.sock --shared-dir=/mnt/user/media/tv --sandbox=none --inode-file-handles=never --log-level=debug 2>&1 | tee /tmp/virtiofsd-tv.log &

Everything seems to work fine, until it crashes for apparently no reason (Last log Entries)

The sockets are just gone without any notification/error:

root@Tower:~# ps aux | grep virtiofsd
root     2116596  0.0  0.0   4192  2304 pts/0    S+   16:30   0:00 grep virtiofsd

these are the sockets right after starting them:

root@Tower:~# dmesg | grep -i "killed process" root@Tower:~#

Anybody got an idea what i can do to fix that?

/usr/bin/virtiofsd --syslog --inode-file-handles=prefer --announce-submounts --socket-path=/tmp/tv.sock --shared-dir=/mnt/user/media/tv --sandbox=none &
seems to work fine, not 100% sure yet but it worked much longer

Never mind did not work

Does anyone have an idea?
