In Bookworm I no longer see the "lock reclaim failed" errors.

Further investigation revealed that the affected installations were also
affected by five-second delays as described here
<https://lore.kernel.org/linux-nfs/59682160-a246-395a-9486-9bbf11686740@mathematik.uni-wuerzburg.de/>.
These show similar symptoms and they also occur on nfs v4.{1,2} only.

So I had to change the lines in <etc/exports> from

| /srv/nfs gss/krb5p(rw,fsid=0,crossmnt,no_subtree_check)

to

| /srv/nfs *(sec=krb5p,rw,fsid=0,crossmnt,no_subtree_check)

Done that and everything runs fine.

In my experience the bug report can be closed.
