Hi. Im hoping someone on here can help me out. I posted something similar to this back in June 2000 and was hoping the 2.4 kernel would provide a fix. Essentially, the problem can be summarized to be that on a machine with ample ram (2G, 4G, etc), I am unable to malloc a gig if I ask for the memory in small ( <= 128k) chunks. I've enclosed some results and a little program which was put together to demonstrate the problems we're having. All of the failures seem to occur around 930MB. I'm more than happy to try any tunings, patches, etc and my time is at your disposal. Thanks, Karl ---- Karl Majer majerNO@SPAMendeca.com Sr Systems Architect 617 577 7999 xt 251 "Think for yourselves and let others enjoy the privilege to do so, too." --Voltaire
