Hello,
I got the following coredump while doing some testing with t_suspend() and t_continue() on
the first INVITE:
(gdb) bt

I suspend the transaction in one route and then I continue it in another route, similar to
below:
route[INVITE]
# Suspend and put to memcache:
t_suspend();
xlog("proceesing suspended in transaction
[$T(id_index):$T(id_label)]\n");
$var(transaction_index)=$T(id_index);
$var(transaction_label)=$T(id_label);
$mct(wait_$tU)= "" + $var(transaction_index) + ":" +
$var(transaction_label);
$mctex(wait_$tU) = 100;
}
route[INVITE_resume] {
# get the transaction index and lable from memcache
$avp(check) = $mct(wait_$tU) ; # I should have the transaction index and the
transaction label here
$var(my_transaction_index) = $(avp(check){s.select,0,:});
$var(my_transaction_label) = $(avp(check){s.select,1,:});
$var(a)= $(var(my_transaction_index){s.int});
$var(b) = $(var(my_transaction_label){s.int});
t_continue( "$var(a)", "$var(b)" , "my_relay_route");
}
route[INVITE_resume] executes only on an asynchronous event (a certain SIP message that
might come or not) .
I use kamailio 4.0.0/Centos Linux. I suspect it happened when I sent CANCEL, but I could
not reproduce. I still have the core file.

Dragos
