Endpoint Expiry synchronization

If Endpoint Expiry began on a particular endpoint, but before it finished, an IQ request was received that referenced that Endpoint, would jitsi-videobridge crash?
I’ve got this problem happening, very occasionally (perhaps every 10, 20 minutes, sometimes not for 90 minutes), for some clients across very shaky connections (mobiles in Africa).
I’m busy trying to patch the code, and am thinking this is the problem, but thought I should check first whether anyone will tell me that’s impossible, or find fault with my reasoning?
