Here's an update about my NFS problem: I added debug options to my kernel, and now that it crashed, I received the following output (can this be saved to file somehow? I'm typing it on another machine right now ;-) Stopped at nfs_nget+0x70: movl 0xc8(%esi),%eax Then did a "trace" at the db> prompt, and this is what I got: nfs_nget(c3d5ac00,c16e904c,1c,e028dd3c,e0d9b900) at nfs_nget+0x70 nfs_lookup(e028de08,e18b98c0,e028deac,c3ea1700,dea62860) at nfs_lookup+0xecf lookup(e028de84,dae62860,2,dea62860,dae62860) at lookup+0x291 namei(e028de84,dae62860,2,e028df80,806b000) at namei+0x19c lstat(dae62860,e028df80,807a24c,806e018,807a200) at lstat+0x41 sycall2(2f,2f,2f,807a200,806e018) at syscall2+0x1f1 Xint0x80_syscall() at Xint0x80_syscall+8x25 Well, I've never had to deal with debugging, but besides the above output, I also have a crash dump. I probably don't know how to extract useful data from there (the section in the FAQ about how to deal with panics is fairly short), however, if someone wants me to send any specific output, just say what it is and I'll send it! Two more things: First of all, the NFS copy operation does *not* always crash at the same file, as I previously said. And the second thing: I have tried Jordan's Apple's file system regression test program, and it ran successfully for three hours without a crash. Strange... If you want any more data, just tell me? I'll probably do some "amateur research" on this problem as well ;-) Greetings Nils -- Nils Holland Ti Systems - FreeBSD in Tiddische, Germany http://www.tisys.org * nils@tisys.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
