Hi
I'm using the TcpSocket ::write to send packets back to a python
program. Once the program received the packet, I see that my controller
CPU is at a high load (increased from ~3% to 95+%). Any clue why this is
happening? The only piece of code I ran was:
const Msg_event& me = assert_cast<const Msg_event&>(e);
Nonowning_buffer buf = ((uint8_t*)rspec_str, strlen(rspec_str));
printf("Writing buffer of size %d\n", strlen(rspec_str));
count_written = me.sock->write(*buf, 0);
printf("Bytes written: %d\n", count_written);
free(rspec_str);
printf("Done freeing\n");
I added a few ugly printf messages in the threads/impl.cc. I see that my
quiet system explodes after the write operation and repeats one set of
code block in an infinite loop.
Log:
----
Writing buffer of size 56
--> co_might_yield_if 0
Bytes written: 56
