I've been seeing quite a few of these recently (often 5 or 6 a day, sometimes more).
Socket Error: recv: Bad file descriptor [-snip address-] (aee4e0a3) Connection denied /boom/ I haven't managed to get a coredump out of it, but running under gdb gives some clues: dfdfdf -> malloc junking -> use-after-free. I forgot to do a 'thread apply all bt', maybe next time, but I thought I'd post this anyway in case someone has any ideas. Program received signal SIGBUS, Bus error.
