Hi! I am trying to use radius as the accounting server for Sip proxy. After i send the Accounting request to radius the radius server brokes down and informs about memory segmentation fault. Please point me what could be the reason for this. Here is the radius debug output: rad_recv: Accounting-Request packet from host 127.0.0.1 port 32825, id=88, length=463 SER-Attr = "" Acct-Session-Id = "69E969D9-A757-D5D1-477F-77FEF8DAA44D@192.168.1.2" Sip-To-Tag = "795669631" SER-From = "tomix <sip:tomix@tezet.no-ip.org:7060>;tag=795669631" SER-Flags = 12 SER-Original-Request-ID = "sip:tomix@tezet.no-ip.org" Sip-Method = "INVITE" Sip-Cseq = 51319 Sip-Translated-Request-ID = "sip:tomix@192.168.1.2:7060" Sip-Source-IP-Address = 192.168.1.2 Sip-From-Tag = "795669631" SER-To = "<sip:tomix@tezet.no-ip.org>;tag=795669631" SER-Digest-Username = "tomix" SER-Request-Timestamp = 1170882487 Calling-Station-Id = "sip:tomix@tezet.no-ip.org:7060" Sip-Source-Port = 7060 SER-Digest-Realm = "tezet.no-ip.org" Sip-Response-Code = 486 Called-Station-Id = "sip:tomix@tezet.no-ip.org" SER-Response-Timestamp = 1170882487 Acct-Status-Type = Failed Service-Type = IAPP-Register NAS-Port = 5060 Acct-Delay-Time = 0 NAS-IP-Address = 127.0.0.1 Processing the preacct section of radiusd.conf modcall: entering group preacct for request 1 Naruszenie ochrony pamięci (translation -> memory segmentation fault) (when I commented out the preprocess module form the preacct it didn't broke down but still nothig was logged in the database) My radiusd.conf file look like this: preprocess { huntgroups = ${confdir}/huntgroups hints = ${confdir}/hints with_ascend_hack = no ascend_channels_per_line = 23 with_ntdomain_hack = no with_specialix_jetstream_hack = no with_cisco_vsa_hack = no } preacct { preprocess acct_unique suffix files } accounting { acc_req_log radutmp sql attr_filter.accounting_response }
