A few questions about your setup, and I'll make a few assumptions (correct me if I am incorrect)
RDServer - holds all the music and mysql database RDNonstop is in your "on-air" studio, used mainly for playout RDStudio1 - is in a production studio, used to edit stuff, logs, put new audio on the system, etc (everything but on-air playout) Is that a fairly correct guess of your setup? Assuming it is, then the questions that come to mind: -What hardware specs / level computer / how much memory / what build of Linux are you using (and is this the broadcast appliance or something else) on the computer showing the issue? -What are the hardware specs on RDServer? -Has the host name lookup stuff in MySQL been turned off, and the system to do all its MySQL stuff directly via the IP address of the MySQL server? -What speed of network are you running (10 / 100 / Gigabit)? Have you checked for network latency? -On the computer that is showing this issue, what sound card(s) are you using? -Are you using Jack, ALSA, or is this an ASI card with the ASI drivers? -Are the drop box folders on RDServer with the dropbox process running on the server, or are they on rdnonstop / rdstudio1 and then the dropbox / import process running locally and transferring the audio data across the network? If the folder itself is on rdnonstop (assuming that's the one which is showing the issue), then there could be some additional network traffic / cpu usage incurred when the system is importing something via those drop boxes -If all your audio is sitting on rdserver, it could be a network issue. Have you checked for network latency issues? -Are there any other processes running on the computer showing the issue that might be eating up either CPU cycles or network bandwidth? (surfing facebook / watching youtube cat videos / etc)? -Assuming this setup is using NFS between the systems for the sharing of /var/snd, have you tried tweaking the settings of NFS (check the list archives - this discussion came up not long ago on this list if I recall correctly). If you're using something else for the networking of /var/snd (Samba for instance), then give NFS a try instead.
