I resolved the problem by providing the proper path for these two configuration items:

modparam("ctl", "binrpc", "unix:/var/run/kamailio_pcscf/kamailio_ctl") modparam("dispatcher", "list_file", "/etc/kamailio_pcscf/dispatcher.list")

I have built kamailio-5.0.3 from source with no issues. I have used the P-CSCF configuration examples from ./misc/examples/pcscf and the database definitions from ./utils/kamctl/mysql.

When I check the configuration file, it is reported to be "ok":

# /usr/local/sbin/kamailio -c loading modules under config path: /usr/local/lib64/kamailio/modules/ 0(10835) INFO: pv [pv_shv.c:60]: shvar_init_locks(): locks array size 16 0(10835) INFO: <core> [core/sctp_core.c:75]: sctp_core_check_support(): SCTP API not enabled - if you want to use it, load sctp module Listening on udp: pcscf.core.ims1.test [172.25.152.20]:4060 Aliases: *: pcscf.core.ims1.test:*

config file ok, exiting...

But when I attempt to run the application, it fails with an error message "ERROR: error while initializing modules":

# /usr/local/sbin/kamailio -D -d loading modules under config path: /usr/local/lib64/kamailio/modules/ Listening on udp: pcscf.core.ims1.test [172.25.152.20]:4060 Aliases: *: pcscf.core.ims1.test:*

WARNING: no fork mode ERROR: error while initializing modules

How can I troubleshoot this to determine what the actual error is? I have tried increasing the debug level, but I don't see any additional information.

Thanks.
