ibmi: failed test case poll_duplex & poll_unidirectional #2698
Description
- Version: all
- Platform: ibmi
They are the last two failed test cases on IBMi PASE.
Debugging shows below code related to the errors --

I added some traces in the action 0&1 code and found the Connection reset by peer error happened in recv() every time when the received bytes exceeds 256.
not ok 1 - poll_duplex
# exit code 393350
# Output from process `poll_duplex`:

# write bytes(0)

# read bytes(148)

# read bytes(256)
# read error: Connection reset by peer
# Assertion failed in ../test/test-poll.c on line 228: r >= 0
I tried to write a simplified C program to recreate the issue but failed. Currently I have to skip action 0&1 on IBMi PASE.
Could someone give me some clue how to find the root cause?
