Situation Description

Percentage of network packets in error is high.

 

Possible Causes
  1. Network interface hardware failures on either the system or downstream on other devices that are on the same sub-net.
  2. Sudden increase in transactional workloads.

 

Suggested Actions

Check your /var/log/messages for signs of hardware failures. Also check other devices on the same sub-net that might be experiencing network interface hardware failures. Check on the health of any networked applications that might be running on that system, including networked filesystems. If the cause of the increased collisions can be narrowed to a particular application, such as NFS or Apache, consider tuning some system parameters. This can include increasing network buffers for better application performance (this might also reduce network collisions). Finally, if you are using wireline connections, double-check all your cable connections and their layout.
