My gut reaction tells me that this is either a kernel stack overflow or out of KVM. The kernel stack overflow problem was "fixed" in 4.4-STABLE some time back (change UPAGES from 2 to 3 in the kernel) so that the kernel stack changes from 4.5K to 8.5K. The other possibility is that he's configured the kernel so big (maxusers too high etc) and he's running out of KVM. No tuning information was supplied (kernel configs, any sysctl/tunable changes etc). I'd be interested to know what this says: # gdb -k /kernel /dev/mem (kgdb) print ((struct vm_map *)kernel_map)->size Cheers, -Peter -- Peter Wemm - peter@FreeBSD.org; peter@yahoo-inc.com; peter@netplex.com.au "All of this is for nothing if we don't go to the stars" - JMS/B5 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
