Troubleshooting

InotifyError exception

Problem

You see a fatal error message similar to the following when starting Virtool:

inotify.calls.InotifyError: Call failed (should not be -1): (-1) ERRNO=(0)

Solution

Virtool uses inotify to keep track of changes to files in its data and watch paths.

This error indicates that the system inotify watch limit is too low. You can increase it.

Open /etc/sysctl.conf and add or update the following configuration line:

fs.inotify.max_user_watches = 524288

Save the changes using the following command:

sudo sysctl -p --system
