SegmentNew() returning null

[mightypanda]

Hi.
I rarely receive a null from the SegmentNew() function in Kcp.cs which turns into a disconnection.
The pool seems to have elements, can a null object be part of the segment collection?

Segment seg = SegmentNew(); seg.conv = conv; seg.cmd = CMD_ACK; seg.wnd = WndUnused(); seg.una = rcv_nxt;

Is there a way to recover from it without disconnecting?
