[Users] Help on probably memory leak

[Marcello Lupo]

Hi to all,
i made some other investigation on my logs.
I found that from one day before the problem of out of memory has been
raised in my logs i found this wrong registrations started to come to
the proxy every 15 seconds from one client.

REGISTER sip:voip.domain.com:5060 SIP/2.0
Via: SIP/2.0/UDP 123.123.123.123:1375;branch=z9hG4bK00E0F55649500000BF2F00001098
From: <sip:voip.domain.com>;tag=00E0F55649500000BF2F00001AB7
To: <sip:voip.domain.com>
Call-ID: 00E0F55649500000AE6C00000408 at 123.123.123.123
CSeq: 59185 REGISTER

In my configuration as route that handle REGISTER requests i made an avp_db_load to check if the username registering
is a valid user and make some avp_check on the preferences that are loaded.

Is it possible that having the empty username in From/To is causing some memory leak?
Remember i'm using version 1.2.0 .
Thanks,
Bye,
Marcello
