[j-nsp] ex4200 throughput trouble on 10GE interface

We ran into a very similar issue with EX-series. The performance drops
drastically and no errors or suspicious counters are increasing.
This happens only in live environment and, no matter how I try, I can't
reproduce it in lab.
We have several switches with similar setup and only one makes the problem.
Tried changing the hardware - no difference. The only clue the that the
problematic switch has ae- (LAG w/ LACP) interface.
Please, share your experience with this problem. Did you find any solution?
Do you know if 9.3 is having this issue?
Any help and clues will be helpful.
