Default Amazon Drive CRC errors with more that 1 chunk

Hello, I have a problem with Amazon Drive. If Chunks is set to 1, files download almost at first try and CRC MD5 verification is correct, but if Chunks is set to some more hight like 4, that is my normal setting, the chance to have the correct MD5 is about 40%.
I have done one download session with a folder containing 14 split parts 100MB and 15 last 40MB (split.aa to split.ao). The first time CRC failed in about 40% (6 files). Second time downloading only 6 parts failed in 4, and the three time I set Chunks to 1 and all 4 download and verifies perfectly.
I have done some:
cmp -bl myoriginal.xx amazon.xx

and it seems that it has some block overlaping, some little example cmp dump:

~$ cmp -bl AngusCompleto.ac.part AngusCompleto.ac

As I see if large blocks matches the original but oders not, some thing is pointing out of sync joining parts, but only with more that 1 Chunk.

The log ID:

25.05.17 03.21.46 <--> 25.05.17 05.22.41 jdlog://0734704015941/

Hi
just ran tests and havent been able to reproduce at all
I downloaded the entire provided folder url
I tested with 4 chunks and 10 chunks without fault.

I see in your logs you have lots and lots of socket issues. do you utilise external harddrives or mapped harddrives over samba or nfs ?

Thanks to raztoki for testing
@goridelta:
I suggest to check some stuff
1.) download with multiple chunks on local disk(no nfs, network,usb)
2.) check firewall/av! (something must cause those network issues)
