[SR-Users] Dispatcher stops working

Hello,
Using Kamailio 5.1.6 for load balancing & failover,
I noticed that from time to time, and very rarely, the dispatcher module
stops dispatching to the Asterisk servers.
I have to execute a "kamcmd dispatcher reload" for it to (re)start working.
This is my dispatcher.list :
1 sip:10.19.XXX.YYY:5060 0 1 duid=sipgw01;maxload=100
1 sip:10.19.XXX.YYY:5060 0 2 duid=sipgw02;maxload=100
1 sip:10.19.XXX.YYY:5060 0 3 duid=sipgw03;maxload=100
1 sip:10.19.XXX.YYY:5060 0 4 duid=sipgw04;maxload=100
This is my dispatch routes:
# Dispatch requests
route[DISPATCH] {
if(!ds_select_dst("1", "10","4"))
{
xlog("L_INFO","no destination selected from dispatcher
list!");
send_reply("404", "No destination");
exit;
}
xlog("L_INFO","going to <$ru> via <$du>\n");
t_on_failure("RTF_DISPATCH");
route(RELAY);
exit;
}
# Sample failure route
failure_route[RTF_DISPATCH] {
if (t_is_canceled()) {
exit;
}
xlog("L_INFO", "Media server $du failed to answer, selecting other
one!");
# next DST - only for 500 or local timeout
if ( t_check_status("500") || (t_branch_timeout() &&
!t_branch_replied()) )
{
#mark the destination Inactive and Probing
ds_mark_dst("ip");
if(ds_next_dst())
{
t_on_failure("RTF_DISPATCH");
route(RELAY);
exit;
}
}
}
I suspect that the ds_mark_dst("ip") command in RTF_DISPACTH is the cause.
Is there any think I can improve on this? Or any know bug with the
dispatcher in Kamailio 5.1.6 version?
Thanks in advance,
*Sérgio Charrua*
