>Description:
Periodically (sometimes every 3-5 minutes) all network connections are stuck and in the same time in /var/log/messages appears a following (the same on the console):
kernel: msk0: Rx FIFO overrun
During these periods of time there is no ping replies, and iftop stops showing info about traffic. It shows blank screen instead of rows of connections.
Simple commands "ifconfig msk0 down; ifconfig msk0 up" does restore normal operation of msk.
