This looks like a bug in midgard, can you please file them
a bugreport too, and report back if you got answer from them?

(You get better backtraces with a static module BTW, please try that too)

also php was configured in this manner:

./configure --disable-xml --with-mysql=/usr/local --with-apxs=/usr/local/apache/bin/apxs --with-midgard=/usr/local --with-imap --enable-debug

and a sample of the apache log:

appears to be a memory leakage problem
