Relay breaking up from source

[ibenarobeno]

I have a relay server set up to relay stream from studio server to listeners. For some reason 1-3 times a week the relay stops and never tries to come back live again though I have set the relayconnectretries to be 100000. I see the following lines in error log:

2014-11-19 06:17:53 INFO [RELAY <ip>:8000/radiofm128 sid=1] Connecting to source relay...
2014-11-19 06:17:53 INFO [RELAY <ip>:8000/radio128 sid=1] Disconnected from SHOUTcast 1 source relay.
2014-11-19 06:18:14 ERROR [RELAY <ip>:8000/radiofm128 sid=1] Connection failure.

My config file looks like this:

unique=radiofm
portbase=80

logfile=C:\SHOUTcast2\stations\$\logs\sc_serv.log
w3clog=C:\SHOUTcast2\stations\$\logs\sc_w3c.log
banfile=C:\SHOUTcast2\stations\$\control\sc_serv.ban
ripfile=C:\SHOUTcast2\stations\$\control\sc_serv.rip

;screenlog=0

allowrelay=0

;password=xyz

streamid=1
streampath=/ringfm
streamrelayurl=http://<ip>:8000/radiofm128
relayconnectretries=100000

Do you have any ideas why the relay connection retry mechanism is not working in this case? To get the radio working again I have to restart the service manually.
