This sounds like a bug I ran into a while back that dealt
with a race of two threads generating the same page
fault at the same time.

I can post the patch but here's something that may
(or may not) help: try linking the offending service
against the static -lc_s library. There's a slim
chance that avoids the problem by causing the
library to page in before the two threads try to
page it in at the same time.

Of course, if that util doesn't use threads, then
all I'm saying here is wrong. If it does use
threads, you can also try to put a little sleep()
at the beginning of each function that's
tfork'd.
