Error log message

[Peter Balsianok]

Hi

I use freeradius 3.0.x (accounting). I found strange error log message

Normal log mode:
Fri Aug  7 15:14:09 2015 : Error: Receive -
Fri Aug  7 15:14:12 2015 : Error: Receive -
Fri Aug  7 15:14:14 2015 : Error: Receive -
Fri Aug  7 15:14:17 2015 : Error: Receive -
Fri Aug  7 15:14:19 2015 : Error: Receive -

When i run radiusd in the debug mode error messages look like:
Debug log mode:
Receive - Length field value too large, expected maximum of 4096 bytes, got
26209 bytes
Receive - Length field value too large, expected maximum of 4096 bytes, got
26209 bytes

Pcap is included in the attachment ( between F5 network element and radius
instance). The network element is testing RADIUS availability.

Thx.
