What's more,I found that the memory occupied by unbound would not be freed when
all requets finished,that means,unbound only consume memory but never free them.
What does unbound hold the memory for?It quite like that a memory leak
happens...
Anyone else has been in the same trouble?
Best Regards,
Tao Ma

Hi Wouter,thanks very much for your reply.
I tried the method you mentioned,here is the info I got from the log:
debug: cache memory msg=16528 rrset=33040 infra=672 val=24888
This info keeps the same from the start of the unbound(I have only about 5
records in unbound).
I also found the value of mem.total.sbrk printed by "unbound-control stats"
keeps growing.The item "mem.total.sbrk" is an estimate of the heap size of
unbound in bytes,it is close to the memory used by unbound.
I have a script keeps recording mem.total.sbrk in a file,and found when
mem.total.sbrk grew to 2017873920,unbound was killed by system(My server has a
2G memory).
Unbound runs in a Gentoo Linux with 2.6.23 kernel,does the problem relate to
the OS?
Thanks & Best regards,
Tao Ma

Hi Tao Ma,
The memory statistics that unbound makes can help?
It prints them into the log file (depending on verbosity
level and --enable-debug to configure) like this:
debug: cache memory msg=1620127 rrset=2964258 infra=738306 val=128832
Also the memory statistics are printed when you enable extended
statistics and do
unbound-control stats, like this:
mem.cache.rrset=2980222
mem.cache.message=1633031
mem.mod.iterator=16460
mem.mod.validator=130126
Best regards,
Wouter
