To me it appears this happens after 2^32 octets. Look attime 12 to 20: 12 to 20: roughly 8 hours at 1200 Kbps: 8*3600*1200*1000/8 = 4320000000 20 to 01: roughly 5 hours at 1800 Kbps: 5*3600*1800*1000/8 = 4050000000 11 to 15:30 : roughly 4.5 hours at 2000 Kbps: 4.5*3500*2000*1000/8 = 3937500000 All these numbers are close to 2^32 which is 4294967296. This doesn't help much but at least the "specific amount of traffic" can now be guessed to be 2^32 octets. Could it be that you are using 64-bit counters that wrap at 2^32 ? > Confidentiality Notice: The information in this document and > attachments is confidential and may also be legally privileged. > It is intended only for the use of the named recipient.
