It turns out that if HTTP response content length is 1024 bytes for this
particular query, "sysread" inside subroutine my_readline of file
Net::HTTP/Methods.pm is returning undef with EAGAIN instead of EOF (0) in
the next sysread loop iteration.
I don't know why it happens with this particular request only, as other
1024 byte response produces EOF as expected.
I have modified sysread($_, 1024, length) with sysread($_, 2048, length) in
Net/HTTP/Methods.pm. Hope increasing read size won't break other things.
Thanks,
Om.
