Hi there, I need some help here to understand why the query in [usrloc_db.c:1084] is empty. This causes the linking of contact to IMPU to fail. I’m using Kamailio 5.0.4. 10(13882) DEBUG: ims_usrloc_scscf [impurecord.c:1284]: unref_subscription_unsafe(): un-reffing subscription [ rafi(a)mnc001.mcc001.3gppnetwork.org] - was [3] 10(13882) DEBUG: ims_registrar_scscf [save.c:519]: update_contacts_helper(): updating the contacts for IMPU < sip:rafi@mnc001.mcc001.3gppnetwork.org> 10(13882) DEBUG: ims_registrar_scscf [save.c:137]: calc_contact_expires(): Calculated expires for contact is 600000 10(13882) DEBUG: ims_registrar_scscf [save.c:548]: update_contacts_helper(): Need to update contact: < sip:rafi@192.168.10.48:57230;transport=udp>: q_value [-1],sos: [0],expires [600000] 10(13882) DEBUG: ims_registrar_scscf [save.c:550]: update_contacts_helper(): packing contact information 10(13882) DEBUG: ims_registrar_scscf [save.c:556]: update_contacts_helper(): adding/updating contact based on prior existence 10(13882) DEBUG: ims_usrloc_scscf [impurecord.c:748]: get_scontact(): looking for contact [sip:rafi@192.168.10.48:57230;transport=udp] in slot 300 10(13882) DEBUG: ims_registrar_scscf [save.c:562]: update_contacts_helper(): inserting new contact 10(13882) DEBUG: ims_usrloc_scscf [impurecord.c:562]: insert_scontact(): INSERTing ucontact in usrloc module 10(13882) DEBUG: ims_usrloc_scscf [ucontact.c:118]: new_ucontact(): Checking param [+g.3gpp.cs-voice] 10(13882) DEBUG: ims_usrloc_scscf [ucontact.c:118]: new_ucontact(): Checking param [+g.3gpp.icsi-ref] 10(13882) DEBUG: ims_usrloc_scscf [ucontact.c:118]: new_ucontact(): Checking param [audio] 10(13882) DEBUG: ims_usrloc_scscf [ucontact.c:118]: new_ucontact(): Checking param [+g.oma.sip-im.large-message] 10(13882) DEBUG: ims_usrloc_scscf [ucontact.c:118]: new_ucontact(): Checking param [+g.3gpp.smsip] 10(13882) DEBUG: ims_usrloc_scscf [ucontact.c:118]: new_ucontact(): Checking param [language] 10(13882) DEBUG: ims_usrloc_scscf [ucontact.c:118]: new_ucontact(): Checking param [+g.oma.sip-im] 10(13882) DEBUG: ims_usrloc_scscf [ucontact.c:118]: new_ucontact(): Checking param [expires] 10(13882) DEBUG: ims_usrloc_scscf [ucontact.c:173]: new_ucontact(): generating hash based on [sip:rafi@192.168.10.48:57230;transport=udp] 10(13882) DEBUG: ims_usrloc_scscf [impurecord.c:280]: mem_insert_scontact(): Created new contact in memory with AOR: [ sip:rafi@192.168.10.48:57230;transport=udp] and hash [300] 10(13882) DEBUG: ims_usrloc_scscf [usrloc_db.c:289]: db_insert_ucontact(): DB: inserting ucontact [sip:rafi@192.168.10.48:57230;transport=udp] 10(13882) DEBUG: ims_usrloc_scscf [usrloc_db.c:311]: db_insert_ucontact(): Converted params to string to insert into db: [+g.3gpp.cs-voice;+g.3gpp.icsi -ref=urn%3Aurn-7%3A3gpp-application.ims.iari.gsma-vs;audio;+ g.oma.sip-im.large-message;+g.3gpp.smsip;language=en,fr;+g. oma.sip-im;expires=600000] 10(13882) DEBUG: ims_usrloc_scscf [udomain.c:843]: ref_contact_unsafe(): incrementing ref count on contact [sip:rafi@192.168.10.48:57230; transport=udp], was 1 10(13882) DEBUG: ims_usrloc_scscf [impurecord.c:1225]: link_contact_to_impu(): number of contacts for IMPU [ sip:rafi@mnc001.mcc001.3gppnetwork.org] is 1 10(13882) DEBUG: ims_usrloc_scscf [usrloc_db.c:1065]: db_link_contact_to_impu(): DB: linking contact to IMPU 10(13882) DEBUG: ims_usrloc_scscf [usrloc_db.c:1084]: db_link_contact_to_impu(): QUERY IS [] and len is 0 10(13882) ERROR: db_mysql [km_dbase.c:128]: db_mysql_submit_query(): driver error on query: Query was empty (1065) 10(13882) ERROR: <core> [db_query.c:181]: db_do_raw_query(): error while submitting query 10(13882) ERROR: ims_usrloc_scscf [usrloc_db.c:1086]: db_link_contact_to_impu(): Unable to link impu-contact in DB - impu [ sip:rafi@mnc001.mcc001.3gppnetwork.org], contact [ sip:rafi@192.168.10.48:57230;transport=udp] 10(13882) ERROR: ims_usrloc_scscf [impurecord.c:1227]: link_contact_to_impu(): Failed to update DB linking contact [ sip:rafi@192.168.10.48:57230;transport=udp] to IMPU [ sip:rafi@mnc001.mcc001.3gppnetwork.org]...continuing but db will be out of sync! 10(13882) DEBUG: ims_usrloc_scscf [udomain.c:852]: unref_contact_unsafe(): decrementing ref count on contact [sip:rafi@192.168.10.48:57230; transport=udp], was 2 Best Regards, Rafael A. _______________________________________________ Kamailio (SER) - Users Mailing List sr-users(a)lists.kamailio.org https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
