I had a typo in my cgi script so that it would only write a newline as the first line, this causes the server to stop as the status check accesses the first array element of the line.

panic: runtime error: index out of range [0] with length 0

goroutine 11 [running]:
main.handleCGI(0x7ad, 0xc0000181c0, 0x11, 0xc000016120, 0x2c, 0xc000016180, 0x2a, 0xc0000162d0, 0x24, 0xc000016300, ...)
