    Issuing the "/users" command during a Synchronet IRC session causes ircd to crash with the same effect/errors as Nelgin's #402 issue.

    This could be reproduced by running ircd from systemd and having a user logged into the BBS. If there is no user, the issue cannot be reproduced. I don't know if it affects ircd running as a service from sbbs.

    This also manifests the issue

    This can lead to a rapid DOS attack by causing the disk to fill since these errors are generated at high speed. more than 7 per second.
