Hello Daniel,
Thanks for the feedback. I think I might have been too quick to blame
htable for this behaviour. In fact, version 5.4 seems to consume more
memory than 5.5 (175129776 bytes vs 20581096), which makes sense since it
has been running for longer (I missed the extra digit previously).
So I'm not sure htable is to blame. On the other hand, I don't see any
other modules using up too much of shmem either, so maybe memory stats
can't provide the answer here?
To answer your question, though, I do use DMQ and both tables that use it
have autoexpire set to the same value on both 5.4 and 5.5:
/etc/kamailio# grep dmq kamailio-module-params.cfg
modparam("dmq", "server_address", "sip:172.30.43.1:5090")
modparam("dmq", "notification_address", "sip:dmq.services.mydomain.com:5090")
modparam("dmq", "multi_notify", 1)
modparam("htable", "enable_dmq", 1)
modparam("htable", "htable",
'cid2hi=>size=8;autoexpire=600;dmqreplicate=1')
modparam("htable", "htable",
'xcid2count=>size=8;autoexpire=600;dmqreplicate=1')
