[Unbound-users] Is there any memory leak in unbound?

[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
