Good day,
Before my workaround (seeb below), clamd started correctly, but as

I tried changing various options, changing MaxThreads to 1, using
TcpAddr instead of LocalSocket; after some googling I found a post
about using LD_ASSUME_KERNEL, and added "export
LD_ASSUME_KERNEL=2.4.1" to just before start-stop-daemon in
init.d/clamav-daemon and now its managed to process several messages
with no problems.
The following : http://people.redhat.com/drepper/assumekernel.html,
seems to imply that the application is broken although given the
fact that clamd would seem to work on host (not u-m-l) linux judging
from the lack of bug reports I assume this has more todo with u-m-l
than clamd. mysqld apparently has the same problem as reported by
somebody else on the same hosting servive I'm using, perhaps other
threaded applications also have this problem.
I've tried stracing and gdbing without success but I've little
experience with debugging threaded applications.
Sincerely,
Adrian Phillips

I think this bug is not glibc's fault - so I close it. Adrian, if you
find something about it from another new point of view, please reopen
it and report it again.
