by I just installed the linux .99pl11 kernel with the net-2 software with
memory debugging turned on. I get messages every 30 seconds that says,
DEB_MALLOC size for 0x487594 given as 102, stored 88, from sock.c:134, last arp.c:534
DEB_MALLOC overran block 0x487594:88, free at sock.c:134, last arp.c534
This change below makes the problem go away for me. I do not know if
this is a "correct" solution because I am new to this code. I mimicked what
was being done elsewhere in the file. This just increases the size of
the malloced buffer.
