Every few hours all Shoutcast1 & sometimes Shoutcast2 streams they keep shutting down & icescc keeps deactiving & not always restarting, this is not always happening with Shoutcast2 & Sctrans.

Icecast streams are not affected.

I have run Permissions command several times

Code: [Select]

/usr/local/centovacast/sbin/fixperms
I have also killed off all icescc , sc_serv , sctrans processes every time the problem arises.

Also  found that any affected streams will start buffering & server load will increase to 4.6 approx after affected  streams are killed off & restarted load returns to 0.85 - 1.0 approx

This problem has only started since upgrading to version 3.04

Any one have any ideas??

Also updated to latest build

Dave

I seem to be having the same issue on SC v2

UPDATE
=====
Problem seems to be Shoutcast V1 / Ices at the moment
Steams only run for roughly 4- 8 hours then autodj deactivates
when you look at the affected streams control panel it shows stream as active , but autodj offline, you then have to stop the steam(s) and restart it.

Also backup(s) fail on affected streams

Should i try updating ices & shoutcast v1

Dave
 

UPDATE 2
=======

Shoutcast 2  / sctrans now also affected again

Just before the autodj shut down the server load increased drastically

Friends, this is a known problem of sc_transV2.
The support Centova say to be a bug regarding TAGS MP3 files outside the default UTF-8. But they do not explain how to correct.
The other problem, and which probably, make the Messrs lose head is in relation to transmission quality live, using the DJ port (this is not aacPlus). Still no solution.
