File : cube.ghost/iolib.c Line : 132, which should contain "newblock();" Action: Append "qp->flg = 1;" to line 132. This bug causes the ghost cube to needlessly delay the sending of the second and succeeding fragments in a multi-fragment message, and makes the sending of long messages (>996 bytes) extremely slow. File : cube.ghost/ghost_rem.c Function: "main()" Location: 3rd lines following "while(1)", which contains "if(acklist) delay = ..." The "delay" variable is the retransmit timer in mille-seconds. If it is set to a value that is too low, the network can become very congested. Set it to a more sensible value, such as 3000. If you do updates over the network, now is a good time to get an update. /*------------------------------------------------------------------------*\ | Wen-King Su wen-king@vlsi.caltech.edu Caltech Corp of Cosmic Engineers | \*------------------------------------------------------------------------*/ Brought to you by Super Global Mega Corp .com
