Problem with graphs when traffic more than 100MB/s

Hello!

I faced the following problem!
I have a problem with graphs when traffic more than 100Mb/s
I use cricket of Version 1.0.5
I can see break-off on graphs and I cannot see graph when traffic more than 100Mb
What sort of problem?
Is it possible to solve it?

Thank you in advance

Yours sincerely,
