Re: [mosquitto-dev] Mosquitto crashing

[Karl Palsson <karlp@xxxxxxxxxxxx>]

There's a variety of crash bugs in various edge cases that have
been fixed since 1.4.2

Have a skim over the changelog and perhaps just try a more recent
version: https://mosquitto.org/ChangeLog.txt 1.4.2 was released
20150507, two and a half years ago.

Sincerely,
Karl P
