i thought more about this problem, maybe it occurs when a big queue of packets have to be processed by recvfrom. the printf can introduce some delay between processing packets, thus the recvfrom queue may reach a huge number. i'm writing some C code to test this case. If its Android please report it to the Android folks. Android differs somewhat significantly from upstream If you can reproduce it in a base upstream kernel then re-open the bug. |
