.BI "ABORT repeated-select-errors"
The main event loop is repeatedly failing. If the server doesn't quit,
it will probably waste all available CPU doing nothing.
+.SP
+.BI "ABORT hash-size-too-large hash " name " size " sz " limit " max
+An internal inconsistency: the hash function
+.I name
+produces a
+.IR sz -byte
+hash, but the server has been compiled to assume that no hash function
+returns more than
+.I max
+bytes.
.SS "ADMIN warnings"
These indicate a problem with the administration socket interface.
.SP
.BI "ADMIN client-write-error " ecode " " message
There was an error sending data to a client. The connection to the
client has been closed.
+.SP
+.BI "ADMIN admin-socket " path " already-in-use"
+The server failed to create the Unix-domain socket object in the
+filesystem, because there's already a socket there, and some other
+process is actively listening for incoming connections.
+.SP
+.BI "ADMIN admin-socket " path " bind-failed " ecode " " message
+The server failed to create the Unix-domain socket object in the
+filesystem for an unusual reason. (The usual reason is
+.BR EADDRINUSE ,
+but this is handled specially.)
+.SP
+.BI "ADMIN admin-socket " path " chmod-failed " ecode " " message
+The server failed to set the correct permissions of the Unix-domain
+socket object.
+.SP
+.BI "ADMIN admin-socket " path " chown-failed " ecode " " message
+The server failed to set the correct ownership of the Unix-domain socket
+object.
+.SP
+.BI "ADMIN admin-socket " path " create-failed " ecode " " message
+The server failed to create its administration socket. This is usually
+because some system resource is unavailable.
+.SP
+.BI "ADMIN admin-socket " path " listen-failed " ecode " " message
+The server failed to arrange to receive incoming connections on its
+Unix-domain socket.
+.SP
+.BI "ADMIN admin-socket " path " name-too-long"
+The server can't create its administration socket, because the chosen
+pathname
+.I path
+is too long. There is, for historical reasons, a rather tight limit on
+the length of name permitted for Unix-domain sockets, usually around 108
+bytes.
+.SP
+.BI "ADMIN admin-socket " path " stat-failed " ecode " " message
+The server failed to create the Unix-domain socket object in the
+filesystem, because there's already something there, but the server
+couldn't discover what.
+.SP
+.BI "ADMIN admin-socket " path " too-many-retries"
+The server failed to create the Unix-domain socket object in the
+filesystem. This error indicates that another process is also
+repeatedly trying to create a Unix-domain socket at the same
+.IR path ,
+and then failing to actually listen for connections on it, but the
+server always loses the applicable race for some reason. This situation
+merits investigation.
+.SP
+.BI "ADMIN adns-init-failed " ecode " " message
+The server failed to initialize the ADNS asynchronous DNS-resolution
+library.
.SS "CHAL warnings"
These indicate errors in challenges, either in the

An error occurred attempting to send a network packet. We lost that
one.

+The server failed to associate a UDP socket with a local address.

+The server failed to create a UDP socket for the

+The server failed to discover the local address for one of its own UDP

+The server failed to configure appropriate buffer sizes on a UDP socket.

+The server failed to configure an IPv6 socket not to try to collect IPv4

The peer sent an encrypted ping response whose id doesn't match any
outstanding ping. Maybe it was delayed for longer than the server was
The helper process sent back a positive response, but didn't include the

+The server couldn't create the socketpair it's supposed to use to
