LNet sometimes sends string twice/skips sending next one in the same
string?

Hey guys!

I am working on a server for my RPi2 which uses LNet to host a TCP
port.

The client will be an iPhone, and I notice that sometimes the iOS app
receives two of the same string or the first sent string and the
second sent string in the same chunk of data.

For example I send the following command once Code:
[Select]myCmd=myValue but the iOS sometimes received Code:
[Select]myCmd=myValuemyCmd=myValue
Why is this happening?

Can I flush the buffer of LNet manually before sending the next
string?
Can I do some error checking to make sure that LNet has sent the
previous string before I proceed sending the next one?

What can be done to assure that my strings are sent as individual
strings?

I made a workaround which basically checks an incoming string if it
contains a potential "double-command" and splits the string into two
strings and then processes those two strings independantly.
