Dan.. thanks for the try :) gave it a shot on one of my relays, the same errors are occurring after restart.. perhaps it's at the source? Stonie mentioned something. .. here's a sampling after the edits and restart

I recently had a similar problem using the GOES-R simulator. Just a guess, but if the data is coming in via UDP and the data rate is higher than it was before then it may be a case of too little kernel buffer space. You can try this (assuming this is Linux): cat /proc/sys/net/core/rmem_max cat /proc/sys/net/core/wmem_max cat /proc/sys/net/core/rmem_default cat /proc/sys/net/core/wmem_default Save these values, if this doesn't help you can reset them. echo 16777216 >/proc/sys/net/core/rmem_max echo 16777216 >/proc/sys/net/core/wmem_max echo 16777216 >/proc/sys/net/core/rmem_default echo 16777216 >/proc/sys/net/core/wmem_default And restart LDM. If this works you can add these values to /etc/sysctl.conf.
