This isn't a DHCP issue. The back-end is slow, and isn't responding to FreeRADIUS. But the client keeps sending DHCP packets, and eventually the server gets into a bad state, and crashes.
The simple fix is to ensure that the back-end is actually replying to the server.
A longer fix is to read the guidelines in the github issue template, and send over a full gdb back trace. We can then try to see what's going on.
But no amount of bug fixing in FreeRADIUS will make your SQL server faster. The first thing you should do is to find out why the SQL server is slow, and fix that.

What type of defect/bug is this?
Crash or memory corruption (segv, abort, etc...)
How can the issue be reproduced?
I used the freeradius module DHCP for my clients. My service crashes several times a day.
OS=Debian10 freeradius=3.0.26 database=oracle clients=80k
At first, I received no error logs, so I thought it was either the database or the driver. Changing Oracle to Postgresql didn't the solve the problem.
Then decided to upgrade Debian10 to Debian12, also didn't the solve the problem.
When I use radiusd -X > /tmp/test.log there are no failures. As I understand it, this is because the service operates in a single-threaded mode
Finally, I rebuilt with the option: --with-experimental-modules --enable-developer, and received a log Error: ASSERT FAILED src/main/threads.c[679]: request->magic == REQUEST_MAGIC
My Config
cat radiusd.conf
thread pool { start_servers = 50 max_servers = 200 min_spare_servers = 5 max_spare_servers = 15 }
cat mods-enabled/sql
sql {

cat sites-enabled/dhcp
dhcp DHCP-Discover {

dhcp DHCP-Request {
