Is there a way to adjust the UDP buffer receive size ?

Are there any other indications of nfacctd not keeping up?

cat /proc/net/udp |egrep drops\|0835

  sl  local_address rem_address   st tx_queue rx_queue tr tm->when retrnsmt   
uid  timeout inode ref pointer drops

52366: 00000000:0835 00000000:0000 07 00000000:00034B80 00:00000000 00000000    
 0        0 20175528 2 ffff89993febd940 7495601

7495601 drops w/ a buffer of 0x0034B80 or 214528
