Subject: xenstored memory leak
Date: Wed, 6 Jul 2016 09:31:38 +0200 [thread overview]
Message-ID: <577CB3DA.1090003@suse.com> (raw)
While testing some patches for support of ballooning in Mini-OS by using
the xenstore domain I realized that each xl create/destroy pair would
increase memory consumption in Mini-OS by about 5kB. Wondering whether
this is a xenstore domain only effect I did the same test with xenstored
and oxenstored daemons.
xenstored showed the same behavior, the "referenced" size showed by the
pmap command grew by about 5kB for each create/destroy pair.
oxenstored seemed to be even worse in the beginning (about 6kB for each
pair), but after about 100 create/destroys the value seemed to be
rather stable.
Did anyone notice this memory leak before?
David, it seems ocaml based xenstore doesn't have such a problem. How
mature is the xenstore Mirage-OS variant? Could it be easily integrated
into the Xen build?
