Hello @henningw and thanks for your help.
As stated in my previous message, the "drop;" is executed after branching, to
be more specific I do something like:
`
t_on_branch(route1)
`
and then
```
branch_route[route1]
{
route(route2);
}
```
inside route2 I invoke rtpengine to open audio ports
```
if(!rtpengine_offer($var(rtpp_flags), "auto-next"))
{
...
route(ROUTE_DROP);
}
```
The mem leak occours when rtpengine_offer() returns false, this causes the
execution of route drop which contains the "infamous" drop; instruction.
```
route[ROUTE_DROP]
{
; do some loggin here
drop;
}
```
When this happens I get some hanging transaction, I can see them using kamctl
`
/usr/sbin/kamcmd tm.list
`
The only way to get rid of them is to run
`
/usr/sbin/kamcmd tm.clear
`
Otherwise they will stay there forever no matter if the transaction got a reply
or not.
I can easily reproduce this on a lab machine, if I replace the
if(!rtpengine_offer($var(rtpp_flags), "auto-next")) line with if (1) I
constantly get mem leak. So i can reproduce the problem quite easily.
