I am writing a program that stresses memory a lot. The program accepts a parameter to indicate how long it runs. For several big values, the program runs OK. But when I give a even bigger one, the system panics at generic_bcopy(). I am wondering whether this has something to do with bad memory chip or some other hardware problem. I do not believe that the program logic will change when given a bigger input. Although I am still studying the code, the chances of a software bug is small. How can I tell if this is due to bad memory? The system is running 4.3-Release and the program runs for about 2 hours. It is a kernel module doing a lot of I/O. Thanks for you advice. -Zhihui To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
