As far as I remember the timers were redesigned in ser recently, to have finer granulation. maybe you can adopt this.
It really strange that ser sometimes send retransmission after 3 ms.

Hello Greg,
the issue comes from the internal timer of openser, it has a fidelity of one seconds, so for the first retransmission it might be under 500ms. Does this issue cause troubles? We are looking to an alternative to improve the timer in this respect, but no timeline at this moment.
Cheers, Daniel

I'm doing an interop test with a well known ITPS, they are kicking back these BYE retransmits, like:

Why is the BYE being sent so quickly? This is an intermediate UAS proxy, and every now and then it spits out an extra BYE like this. Shouldn't this wait 500ms before doing a retry? The rest of the trace is clean. I can forward the whole thing if there is any interest.
