#9526 closed Bug Report (Fixed)

[HANG] "Watch TV" (LiveTV) hangs frontend, shuts down DNS on remote

Reported by: Larry Johnson <keepitsimpleengineer@…> Owned by:
Priority: minor Milestone: 0.24.1
Component: MythTV - Video Playback Version: 0.24-fixes
Severity: medium Keywords: livetv
Cc: Ticket locked: no

Description

This is new behavior. The local system ran for 19 days unattended while I was away, and this behavior occurred upon return.

Selecting "Watch TV" (Live-TV) from the starting Mythtv window opens the splash screen with "Please Wait..." and hangs. This behavior occurs on both local and remote frontends.

On the remote system after Mythtv hang, pinging any website by site name fails with host not found. Ping with IP address succeeds. Closing the window on the remote still leaves frontend processes running, and the frontend cannot be restarted unless the frontend processes are restarted with a SIGTERM. After closing the frontend processes with a SIGTERM ping behavior is normal and the frontend can be restarted.

The backend can record OTA successfully and they can be watched using "Media Library".

Booting the local machine with Windows 7 Media Center LiveTV functions normally.

version info attached; apport bug report attached for remote system.

Ubuntu 10.10, Hauppage 2250, local: nvidia GT260, remote: nvidia GT240

On the remote client system, I ran frontend -r, termout attached.

I changed session-setting to 'MYTHFRONTEND_OPTS="--verbose all,nodatabase"' and ran mythfrontend --service, log attached.

Frontend hangs.

Summary: "Watch TV" (LiveTV) hangs frontend, shuts down DNS on remote → [HANG] "Watch TV" (LiveTV) hangs frontend, shuts down DNS on remote

I do not see how the DNS portion can possibly be caused by MythTV. That sounds more like a dhcpd that died somewhere on your network, and that machine couldn't renew its IP address.

The remainder of this ticket seems to be right along the lines of something markk recently fixed. Try updating to the tip of the fixes/0.24 branch, and try again. Please let us know if this is now solved.

I see now that my earlier report was very unclear. As of… :~$ mythbackend --version MythTV Version : v0.24-159-gb259732 MythTV Branch : fixes/0.24 :~$ mythfrontend --version MythTV Version : v0.24-159-gb259732 MythTV Branch : fixes/0.24 …it has been working.
