Hm, that's interesting.  Can you get a stack trace from that process?

9.3.what exactly?

(You do know that 9.3.x is out of support, so even if this investigation
reveals a bug, we're not going to fix it in 9.3.x.  I'm willing to look
anyway on the chance that there's a bug that also affects later versions.)
