I have a Mosquitto instance (calling this MClient) bridged to another
Mosquitto instance (calling this one MServer).

Everything is working fine if MServer is started before MClient, but if
MClient is already running before the MServer, the result is a failing
MClient instance. The failed connects are expected, but the failing
assertion is not. Here's MClient's output:

/usr/sbin/mosquitto: loop.c: 291: loop_handle_reads_writes: Assertion
`pollfds[db->contexts[i]->pollfd_index].fd == db->contexts[i]->sock'
failed.

Note: The connection from 127.0.0.1 is something different/unrelated, as
MClient is certainly running on a different machine than the MServer. Some
details from Mosquitto.conf (no encryption set):

connection my_named_connection
topic # out
start_type lazy
#idle_timeout 60
threshold 2
username test_username
password test_password

Note: I believe the problem to be related to MClient as substituting the
Mosquitto instance at MServer with a MQTT.js instance gives the same result
(see also https://github.com/adamvr/MQTT.js/issues/74) . MServer however
also picks up on the problem when MClient connects:

pave@CIB-flukso:~/perpetual/mosquitto_tests/mosquitto-1.1.3/src$ ./mosquitto
1368635611: mosquitto version 1.1.3 (build date 2013-05-08

1368635612: Socket read error on client flukso-d7dc7f.perpetual, disconnecting.

MServer however keeps running, and after restarting the MClient both live
happily together (that is of course if MServer isn't brought down and up).
Ps: The MClient is running on a Flukso device (see flukso.net) and bridged
to MServer running on Ubuntu 12.04 (Precise Pangolin).
