[mythtv-users] mythbackend crashes every 6-7 hours

[Rob Verduijn]

Hi,

I've taken some time to dig into mythweb and the errors.
I think I've fixed it now.
(I put the symbolic links in the mythweb data dir not my own data
dir.......that will teach me to use unique names)
Mythweb gives no more errors and there are no circular links.

Still watching mythbackend to see if it is stable now.

I'll keep ya posted if it runs through the night.
