Frequent frontend lockups on 0.25 / 10.04 LTS

[andrewc6l]

I see someone else has a thread (http://ubuntuforums.org/showthread.php?t=1971260) on frequent frontend lockups on 0.25 with Precise. But I'm using 10.04 LTS and see something similar: at random times, mythfrontend just goes away - I get a blank screen and nothing in the log. It's still running, though.

If I kill mythfrontend.real and restart it, then things work again... but the WAF is getting lowered

Logs aren't really helpful:

(at this point I killed mythfrontend.real, and it restarted with no problems):

May  5 12:52:11 mythtv mythfrontend[9450]: C thread_unknown mythcommandlineparser.cpp:2534 (ConfigureLogging) mythfrontend version: fixes/0.25 [v0.25-65-g2e2f02e] www.mythtv.org

I'd be suprised if the NWS-Alerts update is the culprit (but maybe it is... that seems to be what's happening before every crash in my log). I am using NVIDIA as well. Is turning off realtime priority threads an option on 10.04? Has anyone else run into this?

Maybe I'll try uninstalling mythweather to see if that solves the problem.
