Perhaps there is a bug in your C program and it only works sometimes.
There is *no* misuse of socket APIs which the Python client could be
committing which would cause a correctly written server (in C or any
other language with BSD socket APIs) to fail. I suggest investigating
how telnet and your Python client differ, then looking into the C code
to find out how that difference can trigger a bug in it.
