<!-- Kamailio Project uses GitHub Issues only for bugs in the code or feature requests. Please use this template only for feature requests. If you have questions about using Kamailio or related to its configuration file, ask on sr-users mailing list: * https://lists.kamailio.org/mailman3/postorius/lists/sr-users.lists.kamailio… If you have questions about developing extensions to Kamailio or its existing C code, ask on sr-dev mailing list: * https://lists.kamailio.org/mailman3/postorius/lists/sr-dev.lists.kamailio.o… Please try to fill this template as much as possible for any issue. It helps the developers to troubleshoot the issue. If you submit a feature request (or enhancement) add the description of what you would like to be added. If there is no content to be filled in a section, the entire section can be removed. Note that a feature request may be closed automatically after about 2 months if there is no interest from developers or community users to implement it, being considered expired. In such case can be reopened by writing a comment that includes the token `/notexpired`. About two weeks before considered expired, the item is marked with the label `stale`, trying to notify the submitter and everyone else that might be interested in it. To remove the label `stale`, write a comment that includes the token `/notstale`. Also, any comment postpone the `expire` timeline, being considered that there is interest in the proposed feature request. You can delete the comments from the template sections when filling. You can delete next line and everything above before submitting (it is a comment). --> ### Description <!-- Explain what you did, what you expected to happen, and what actually happened. --> ### Expected behavior large "key_value" can store to db_sql。 #### Actual observed behavior the key_value = "{\"id\":1,\"in_port\":\"5263\",\"in_ptl\":\"udp\",\"rate_limit\":\"\",\"out_port\":\"5262\",\"out_ptl\":\"udp\",\"mode\":2,\"proxied_ip\":\"172.16.4.114\",\"proxied_port\":\"5080\",\"in_gateway_ip\":\"116.198.229.196\",\"in_gateway_port\":\"5080\",\"black_list\":{\"ip\":[\"127.0.0.1\"],\"user\":[]},\"white_list\":{\"ip\":[\"127.0.0.1\"],\"user\":[]},\"called_prefix\":[{\"match_num\":\"\",\"caller_rule\":{\"start_pos\":0,\"length\":2,\"new_num\":\"\",\"type\":2},\"called_rule\":{\"start_pos\":0,\"length\":0,\"new_num\":\"\",\"type\":0}}],\"caller_prefix\":[{\"match_num\":\"\",\"caller_rule\":{\"start_pos\":0,\"length\":2,\"new_num\":\"\",\"type\":1},\"called_rule\":{\"start_pos\":0,\"length\":0,\"new_num\":\"\",\"type\":0}}]}" <img width="913" alt="企业微信截图_17234562508919" src="https://github.com/user-attachments/assets/ab0acd4b-980a-4dc5-95b… #### Debugging Data ``` (paste your debugging data here) ``` #### Log Messages <!-- Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` (paste your log messages here) ``` #### SIP Traffic <!-- If the issue is exposed by processing specific SIP messages, grab them with ngrep or save in a pcap file, then add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site). --> ``` (paste your sip traffic here) ``` ### Possible Solutions <!-- If you found a solution or workaround for the issue, describe it.
