[Kamailio-Users] Kamailio is loosing all registrations

Hello to all I have been using Kamailio for a long time, but now some of my clients aren't registering... I see the REGISTER packets coming in the server (with ngrep), but Kamailio doesn't answer. I'm not using persistent storage, so all registrations are in memory. But when Kamailio reaches 30 or more registrations... it just stops answering and looses all registered clients: [root@server ~]# kamctl ul show | grep records Domain:: location table=512 records=4 max_slot1 I have disk space, could this be lack of memory? [root@server ~]# free -m total used free shared buffers cached Mem: 748 630 118 0 148 391 -/+ buffers/cache: 90 658 Swap: 1503 0 1503 There are no errors in /var/log/kamailio How can I be sure of whats the problem? Thanks Regards Joao Pereira
