I am still getting the catch ups after having ruled out these issues: * I reniced icecast and LS * I checked that my NTP daemon works and uses skew/drift * I now keep the connection to LS open avoiding therefore the logging output Yet, I get these lines: > 2013/06/20 00:14:40 [clock.wallclock_main:2] We must catchup 1.78 seconds! > 2013/06/20 06:08:00 [clock.wallclock_main:2] We must catchup 1.06 seconds! > 2013/06/20 06:55:00 [clock.wallclock_main:2] We must catchup 1.32 seconds! > 2013/06/20 07:23:25 [clock.wallclock_main:2] We must catchup 1.12 seconds! > 2013/06/20 07:34:32 [clock.wallclock_main:2] We must catchup 1.17 seconds! > 2013/06/20 08:07:21 [clock.wallclock_main:2] We must catchup 1.02 seconds! > 2013/06/20 08:20:14 [clock.wallclock_main:2] We must catchup 1.14 seconds! > 2013/06/20 09:21:12 [clock.wallclock_main:2] We must catchup 1.02 seconds! > 2013/06/20 09:30:05 [clock.wallclock_main:2] We must catchup 1.21 seconds! > 2013/06/20 09:50:19 [clock.wallclock_main:2] We must catchup 1.43 seconds! > 2013/06/20 11:11:48 [clock.wallclock_main:2] We must catchup 1.08 seconds! > 2013/06/20 12:42:51 [clock.wallclock_main:2] We must catchup 1.01 seconds! The process itself only needs 40% CPU of 400% (dual core, dual threaded). As I said before, I am reading a stream and writing 2 streams from/to the same icecast server. And the catchup seems to happen when the metadata HTTP-GET is sent to icecast.
