You wont be able to parse it. I believe sockstat was written when
username was limited to 8 chars. Therefore, it will count until the 9th
position to print another space.
I dont know if patching is an option for you, but you can truncate the
username printing up to 8 chars. This is the huge patch which will make
your output look better and get fully parseable:
