One server replicates to others with t_replicate_tcp. The connection was by mistake blocked by a firewall and after a few hours the memory of Kamailio ran out, with over 40000 open transactions in tm.stats on a server with around 300 registrations and no calls since restart.
t_replicate transactions needs to time out somehow.

### Description
<!--
Have a problem with cnxcc call monitoring.
__set_max_credit() allocates new call as expected:
"DEBUG: cnxcc [cnxcc_mod.c:444]: __dialog_created_callback(): Flag is not
set for this message. Ignoring
DEBUG: cnxcc [cnxcc_mod.c:1569]: __set_max_credit(): Setting up new call

DEBUG: cnxcc [cnxcc_mod.c:1255]: __alloc_new_call_by_money(): New call
allocated for client [2]".
So that I can see values inside redis:
redis.youwillnever.find:6389> HGETALL cnxcc:money:2
1) "concurrent_calls"
2) "0"
3) "consumed_amount"
4) "0.000000"
5) "ended_calls_consumed_amount"
6) "0.000000"
7) "max_amount"
8) "0.000000"
9) "number_of_calls"
10) "1"
11) "type"
12) "1"
But cnxcc doesn't update credit amount during the call.
modparam("debugger", "mod_level", "cnxcc=4") but there are no rows in
kamailio log like:
"DEBUG: cnxcc [cnxcc_check.c:94]: check_calls_by_money(): ec=0.000000,
ca=0.600000, ca2=0.600000
DEBUG: cnxcc [cnxcc_check.c:107]: check_calls_by_money(): Client
[some_client] | Ended-Calls-Credit-Spent: 0.000000 TotalCredit/MaxCredit:
0.600000/3.000000".
cnxcc parameters:
modparam("cnxcc", "dlg_flag", FLG_DLG)
modparam("cnxcc", "redis", "addr=redis.youwillnever.find;port=6389;db=0")
modparam("cnxcc", "credit_check_period", 1)
function that performs credit setup:
if
(!cnxcc_set_max_credit("$var(setid)","$var(credit)","$var(cost_per_sec)","$var(i_pulse)","$var(f_pulse)"))
{
xlog("L_WARN", "----- cnxcc: $fU - Error setting up credit
control - R=$ru ID=$ci\n");
sl_send_reply("402", "Payment Required");
}
Why is it so? And as see, all values are set zero. Seems to be problem with
redis inserts.
Any ideas are highly appreciated. Thanks.
