I ran into a similar problem with the BSD allocator running under heavy
load that didn't happen under any Solaris or Linux system I used. I
finally fixed it by using Doug Lea's malloc just for this one
application:

This was under FreeBSD 6.*, but it might provide another data point if
you
want to give it a try.

I'm not sure how similar the two problems are. I quite frankly know
_very_ little
