My concern is that this figure reflects requests which are not handled at all (prior to the expiration of some timer and a retransmission) because there are no worker threads able to get to them. Is it possible?
No, if there is no worker to handle the packet, then it is not known that it was dropped (in case it was from network buffer) or if it is was already in transactions hash table, there has to be a kamailio process getting it out of there.
A reason that could be for dropping is the case of invalid sip messages -- initial parsing fails and the message doesn't get to routing script.
