<!-- Kamailio Project uses GitHub Issues only for bugs in the code or feature requests. Please use this template only for bug reports. 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. Note that an issue report may be closed automatically after about 2 months if there is no interest from developers or community users on pursuing it, being considered expired. In such case, it can be reopened by writing a comment that includes the token `/notexpired`. About two weeks before considered expired, the issue 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 pursuing the issue. If there is no content to be filled in a section, the entire section can be removed. 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). --> ### Start up failed with error " waiting for child one too long" execute start up command, and suddenly failed. ` sudo /usr/local/sbin/kamailio -m 128 -M 8 -E -e -dd -f /usr/local/etc/kamailio/kamailio.cfg ` ### Troubleshooting #### Reproduction Maybe the problem of my env. #### Debugging Data #### Log Messages the log: 0(2749) INFO: <core> [core/sctp_core.c:74]: sctp_core_check_support(): SCTP API not enabled - if you want to use it, load sctp module Listening on udp: 192.168.5.167:5061 Aliases: udp: 192.168.5.167:5061 0(2749) INFO: <core> [core/tcp_main.c:5218]: init_tcp(): using epoll_lt as the io watch method (auto detected) 0(2751) INFO: rr [../outbound/api.h:53]: ob_load_api(): unable to import bind_ob - maybe module is not loaded 0(2751) INFO: rr [rr_mod.c:185]: mod_init(): outbound module not available 0(2751) WARNING: db_mysql [km_my_con.c:187]: db_mysql_new_connection(): opt_ssl_ca option not supported by mysql version (value (null)) - ignoring 0(2751) INFO: auth [auth_mod.c:342]: mod_init(): qop set, but nonce-count (nonce_count) support disabled 0(2751) WARNING: db_mysql [km_my_con.c:187]: db_mysql_new_connection(): opt_ssl_ca option not supported by mysql version (value (null)) - ignoring 0(2751) WARNING: tls [tls_mod.c:364]: mod_init(): tls support is disabled (set enable_tls=1 in the config to enable it) 0(2751) INFO: <core> [main.c:3233]: main(): processes (at least): 24 - shm size: 134217728 - pkg size: 8388608 0(2751) INFO: <core> [core/udp_server.c:163]: probe_max_receive_buffer(): SO_RCVBUF is initially 16777216 for fd 9 0(2751) INFO: <core> [core/udp_server.c:233]: probe_max_receive_buffer(): SO_RCVBUF is finally 16777216 on fd 9 0(2751) INFO: <core> [core/udp_server.c:264]: probe_max_send_buffer(): SO_SNDBUF is initially 16777216 for fd 9 0(2751) INFO: <core> [core/udp_server.c:334]: probe_max_send_buffer(): SO_SNDBUF is finally 16777216 on fd 9 1(2754) WARNING: db_mysql [km_my_con.c:187]: db_mysql_new_connection(): opt_ssl_ca option not supported by mysql version (value (null)) - ignoring 1(2754) NOTICE: ndb_redis [redis_client.c:257]: redisc_init(): Connecting to 10.20.80.33:6380 0(2751) ERROR: <core> [main.c:1825]: main_loop(): waiting for child one too long - wait time: 1000000 1(2754) INFO: <core> [main.c:888]: sig_usr(): signal 15 received 0(2751) INFO: snmpstats [snmpstats.c:399]: mod_destroy(): The SNMPStats module got the kill signal 0(2751) INFO: snmpstats [snmpstats.c:403]: mod_destroy(): Shutting down the AgentX Sub-Agent! 0(2751) INFO: <core> [core/sctp_core.c:53]: sctp_core_destroy(): SCTP API not initialized` what does that mean? ` 0(2751) ERROR: <core> [main.c:1825]: main_loop(): waiting for child one too long - wait time: 1000000` How can I solve that? #### SIP Traffic ### Possible Solutions ### Additional Information * **Operating System**: ` LSB Version: :core-4.1-amd64:core-4.1-noarch Distributor ID: CentOS Description: CentOS Linux release 7.9.2009 (Core) Release: 7.9.2009 Codename: Core ` Kamailio-5.8.2 -- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/3960 You are receiving this because you are subscribed to this thread.
