[SR-Users] Kamailio stops responding after 10 days or so

Hi! Kamailio 3.0.3. I have a strange problem with one of our Kamailio servers. This one is used for routing (with carrierroute) and to send presence information (with pua module) Once every 10 day or so I get this error and then Kamailio stops responding to any SIP packets. Apr 6 08:05:48 sip-core-1 /usr/local/sbin/kamailio[9186]: WARNING: <script>: Failure route - M=INVITE RURI=sip:8615XXXX@178.XX.XX.XX F=sip:861XXXXX@188.120.93.114:1025 T=sip:86155XXXX@sip1.uni-tel.dk IP=178.XX.XX.XX ID=6de881ec07f9c6494ee589cf208da358(a)10.11.87.206 Apr 6 08:05:48 sip-core-1 /usr/local/sbin/kamailio[9186]: ERROR: carrierroute [cr_func.c:95]: cannot find AVP 'carrier' Apr 6 08:05:48 sip-core-1 /usr/local/sbin/kamailio[9186]: ERROR: carrierroute [cr_func.c:805]: invalid carrier id -1 Apr 6 08:05:48 sip-core-1 /usr/local/sbin/kamailio[9186]: ERROR: <script>: cr_next_domain failed Shared memory size is 128M and over halv is free just before the error. The server is in production and does handle debug>1 well, so I do not have much information in the log files. Private memory is the default size. Any ideas what it could be, or how to investegate further? I think my next steps would be to increase the private memory og to increase children=4 to children=8 -- Morten Isaksen
