Hello,
Thank you for this suggest. I will try it tomorrow.
About the firewall/system, what are that parameters can affect this behaviour? I was working with RHEL5.3 and I never seen this issue. It’s the first time that I work on RHEL6.
Regards,
Igor.

Hello,
if you can give a try with master branch, try to set in addition the parameter modinit_delay which is taking same kind of value.
Otherwise, you have to change your firewall/system policies in terms of new connections rate.
Cheers,
Daniel

Hello Daniel,
I tried this parameter but without success. Even if I set the parameter to 15000, the process won’t start.

Hello,
try with this global parameter:

I test with children=1 and it works (result in 6 MySQL connections!). But it would be insufficient for production uses.
How can we grow the number of children and keep Kamailio working?

Igor.

Objet : Kamailio 4.0.4 won't start
Hello,
I don’t figure out why Kamailio can’t connect to MySQL DB.
DBURL is set :
# *** Value defines - IDs used later in config
#!ifdef WITH_MYSQL
# - database URL - used to connect to database server by modules such
# as: auth_db, acc, usrloc, a.s.o.
#!define DBURL "mysql://kamailio:PASSWORD@192.168.2.6/kamailio"
#!endif
Each module refer to DBURL, like acc :
# ----- acc params -----
/* what special events should be accounted ? */
modparam("acc", "early_media", 0)
modparam("acc", "report_ack", 1)
modparam("acc", "report_cancels", 1)
/* by default ww do not adjust the direct of the sequential requests.
if you enable this parameter, be sure the enable "append_fromtag"
in "rr" module */
modparam("acc", "detect_direction", 0)
/* account triggers (flags) */
modparam("acc", "log_flag", FLT_ACC)
modparam("acc", "log_missed_flag", FLT_ACCMISSED)
modparam("acc", "log_extra",
"src_user=$fU;src_domain=$fd;src_ip=$si;"
"dst_ouser=$tU;dst_user=$rU;dst_domain=$rd")
modparam("acc", "failed_transaction_flag", FLT_ACCFAILED)
/* enhanced DB accounting */
#!ifdef WITH_ACCDB
modparam("acc", "db_flag", FLT_ACC)
modparam("acc", "db_missed_flag", FLT_ACCMISSED)
modparam("acc", "db_url", DBURL)
modparam("acc", "db_extra",
"src_user=$fU;src_domain=$fd;src_ip=$si;"
"dst_ouser=$tU;dst_user=$rU;dst_domain=$rd")
#!endif
When I try a connection from MySQL CLI with the same login and password, it works.
Here are the output from /var/log/messages (note that public IP address appears as A.B.C.X) :
