SHOUTcast DNAS 2.2 (Build 107) 10/16/2013 *** Forum Exclusive ***

I discovered something "new" (for me at least), that may help you...

Since Friday afternoon, my server started to be VERY unstable, with sc_serv freezing/halting every 5 minutes or so.
Ubuntu's and sc_serv's logfiles didn't give any hint, so I tried everything, from reinstalling Shoutcast DNAS, to replacing config files, changing install location, modifying resources and so on, but... nothing helped!

What I realized is that for sure it was not a "DST client" side problem, because the listeners count never reached more than 10..20 simultaneous connections between freezes.

Therefore, I checked the "SRC clients" and found that one radio station (running on a Windows XP virtual machine) was partially blocked due to "virtual memory full" error.
Basically, connection to the server was established and a "no data flow" (or maybe corrupted data) kept on feeding sc_serv, which shortly after stopped working.

After fixing the virtual machine, sc_serv is running again like a charm!

So, it looks like data transfer problems/errors on the source side cause sc_serv to become very unstable, much more than destination clients' (bad/repeated) requests management issues described in my previous posts.

Cheers!
Cande
