Re: [Users] No memory left errors and Private Memory Size

Thanks for you reply. On further examination of the very basic logging information I could find on that server, I am inclined to agree with your theory that it may be a particular UA causing these errors. The logs seem to show that this particular error is only generated shortly after this particular UA attempts registration, as before and after that, there were no such errors for other users. Further more, This error is only generated for Registration atempts and does not seem to occur during call setup, INVITES, etc. - which makes sense from the error descriptoin which seems to be implying that Openser is having trouble creating/building the contact header for the REGISTER. The errors are almost certainly to do with this UA as I have just counted over 20 instances all occurring only after this UA. I will certainly look more into this to confirm this. The trouble is this often happens fairly late at night when every one is asleep, making it hard to get a live trace as I don't know when exactly this guy is going to connect, but I'll see what I can do. Unfortunately, we took off most of the syslog logging from the server as syslog performance was becoming an issue with performance (read one of my previous posts :)), so I can't get a full packet dump from the openser server itself. Looking further into this I managed to pull up some Ethereal traces from a different machine we use for tracing and loggin on the same network, and the device seems to be a Sipura SPA 2002-3.1.2(a). Since I can't find a Register message, I can only show you an INVITE but I guess it will still have the same contact header as we are not overwriting the contact information anywhere I know of: Session Initiation Protocol Request-Line: INVITE sip:5068831424@<SIP AS>:5060 SIP/2.0 Method: INVITE Resent Packet: False Message Header Record-Route: <sip:<OPENSER IP>;ftag=935c557f841a75c7o0;lr=on> Via: SIP/2.0/UDP <OPENSER IP>;branch=z9hG4bK2f26.41279b67.0 Via: SIP/2.0/UDP 192.168.1.100:16384;rport=16384;received= 165.98.158.187;branch=z9hG4bK-b8411887 From: <sip:071159040628330829@<OPENSER DOMAIN>>;tag=935c557f841a75c7o0 SIP from address: sip:071159040628330829@<OPENSER DOMAIN> SIP tag: 935c557f841a75c7o0 To: <sip:5068831424@<OPENSER DOMAIN>> SIP to address: sip:5068831424@<OPENSER DOMAIN> Call-ID: a0a739df-fb05dce7(a)192.168.1.100 CSeq: 101 INVITE Max-Forwards: 69 Contact: <sip:071159040628330829@165.98.158.187:16384> Expires: 240 User-Agent: Sipura/SPA2002-3.1.2(a) Content-Length: 428 Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS, REFER Supported: x-sipura Content-Type: application/sdp Message body Session Description Protocol Session Description Protocol Version (v): 0 Owner/Creator, Session Id (o): - 11350715 11350715 IN IP4 192.168.1.100 Owner Username: - Session ID: 11350715 Session Version: 11350715 Owner Network Type: IN Owner Address Type: IP4 Owner Address: 192.168.1.100 Session Name (s): - Connection Information (c): IN IP4 192.168.1.100 Connection Network Type: IN Connection Address Type: IP4 Connection Address: 192.168.1.100 Time Description, active time (t): 0 0 Session Start Time: 0 Session Stop Time: 0 Media Description, name and address (m): audio 16402 RTP/AVP 4 0 2 8 18 96 97 98 100 101 Media Type: audio Media Port: 16402 Media Proto: RTP/AVP Media Format: ITU-T G.723 Media Format: ITU-T G.711 PCMU Media Format: ITU-T G.721 Media Format: ITU-T G.711 PCMA Media Format: ITU-T G.729 Media Format: 96 Media Format: 97 Media Format: 98 Media Format: 100 Media Format: 101 Media Attribute (a): rtpmap:4 G723/8000 Media Attribute Fieldname: rtpmap Media Attribute Value: 4 G723/8000 Media Attribute (a): rtpmap:0 PCMU/8000 Media Attribute Fieldname: rtpmap Media Attribute Value: 0 PCMU/8000 Media Attribute (a): rtpmap:2 G726-32/8000 Media Attribute Fieldname: rtpmap Media Attribute Value: 2 G726-32/8000 Media Attribute (a): rtpmap:8 PCMA/8000 Media Attribute Fieldname: rtpmap Media Attribute Value: 8 PCMA/8000 Media Attribute (a): rtpmap:18 G729a/8000 Media Attribute Fieldname: rtpmap Media Attribute Value: 18 G729a/8000 Media Attribute (a): rtpmap:96 G726-40/8000 Media Attribute Fieldname: rtpmap Media Attribute Value: 96 G726-40/8000 Media Attribute (a): rtpmap:97 G726-24/8000 Media Attribute Fieldname: rtpmap Media Attribute Value: 97 G726-24/8000 Media Attribute (a): rtpmap:98 G726-16/8000 Media Attribute Fieldname: rtpmap Media Attribute Value: 98 G726-16/8000 Media Attribute (a): rtpmap:100 NSE/8000 Media Attribute Fieldname: rtpmap Media Attribute Value: 100 NSE/8000 Media Attribute (a): rtpmap:101 telephone-event/8000 Media Attribute Fieldname: rtpmap Media Attribute Value: 101 telephone-event/8000 Media Attribute (a): fmtp:101 0-15 Media Attribute Fieldname: fmtp Media Attribute Value: 101 0-15 Media Attribute (a): ptime:30 Media Attribute Fieldname: ptime Media Attribute Value: 30 Media Attribute (a): sendrecv On 02/01/07, Andreas Sikkema &lt;andreas(a)ramdyne.nl&gt; wrote:
