Hi,
I deployed our app on 9.9.0 this morning and after initializing a crawl of the
page I ended up getting a low quote of 503s.
The 503s are always the same:
2022-03-31 09:35:05,031 ERROR [org.apache.wicket.DefaultExceptionMapper]
Unexpected error occurred

Any idea how to debug this or where it may come from (race condition in our
code as wicket became faster?)?
It somehow seems to be a happen when requests coming in at the same time....
with 9.8.0 we got no such errors.
Best,
