Do you have CONFIG_CHECKPOINT_RESTORE enabled? Does it go away if you
disable it?
I think I foud at least one bug in the MSG_COPY stuff: it leaks the
"copy" allocation if
mode == SEARCH_LESSEQUAL
but maybe I'm misreading it. And that shouldn't cause the problem you
see, but it's indicative of how badly tested and thought through the
MSG_COPY code is.
Totally UNTESTED leak fix appended. Stanislav?
