Here's some more info on the spontaneous crashes we're seeing under 2.2.7. They seem to happen during times of heavy CPU and memory loads; the crash this morning occurred when we were doing a backup of the entire disk. We do our daily backups by piping the output of dump through gzip -9 and then through FTP to a hard disk on another machine. Just before our OS upgrade we did several such backups for safety; none of them caused a crash. The reboots leave the file system a bit inconsistent. At one point, with a kernel that was built slightly differently, we got error messages saying "malloc(): recursive call" (or something similar). Once, we saw a panic screen that described a virtual memory error; it flashed just before the reboot. Has anyone else seen these? I'm concerned that there might be a VM problem in 2.2.7. (We can't see any signs of flaky hardware.) --Brett To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
