[mythtv-users] MBE deadlocks and Possible SSDP Reflection attempt

[Dave Badia]

I've been seeing a lot of the "Protocol version check failure" messages on
my SBEs and have intermittant freezes on my frontends.  The frontends will
show recordings as not available, but then after a minute or so, the same
recording will play ok.

2014-11-10 14:24:59.000219 C [12270/12318] ProcessRequest
mythcorecontext.cpp:1214 (CheckProtoVersion) - Protocol version check
failure.
            The response to MYTH_PROTO_VERSION was empty.
            This happens when the backend is too busy to respond,
            or has deadlocked due to bugs or hardware failure.


I see a ton of these in my MBE logs, although I can't necessarily correlate
these with the SBE freezes/errors:

SDP ssdp.cpp:339 (ProcessData) - SSDP Request from WAN IP address
(0.0.0.0). Possible SSDP Reflection attempt. Ignoring as security risk.



Full SBE error

Anyone else seeing this with recent 27-fixes b305eb5 or later?

Thanks
