hammer-inodes: malloc limit exceeded

[Francois Tigeot <ftigeot@xxxxxxxxxxxx>]

Hi,

I have replaced my backup system with a new machine running DragonFly and
Hammer. It is a SMP Opteron with 2GB memory. The backup partition is a
single disk on a 3Ware RAID controler.

The previous machine (FreeBSD 7/UFS2) ran rsnapshot every 4 hours and this
one continues with the same configuration. I have copied the content of the
old rsnapshot directory to the new backup disk before puting it in production.

For details on rsnapshot, see http://www.rsnapshot.org/

/backup is a 400GB Hammer disk:

Filesystem  Size   Used  Avail Capacity iused   ifree %iused
Backup      371G   239G   132G    64% 2652953       0  100%

I have just encountered this panic:

panic: hammer-inodes: malloc limit exceeded
mp_lock = 00000000; cpuid = 0
panic
panic
kmalloc
hammer_get_inode
hammer_vop_nresolve
vop_nresolve
cache_resolve
nlookup
kern_stat
sys_lstat
syscall2
Xint0x80_syscall
Debugger("panic")

The backtrace was quickly copied by hand. I may be able to post the full trace
tomorrow if needed.
