Hi!I think that there will be much better contributions than mine, but I give a hint to start with the debug.
A recent thread was about a memory leak http://comments.gmane.org/gmane.comp.web.haproxy/19995.
In that case "OpenSSL sometimes acts stupidly [...] inside a chroot". Could the one that you described be another strange behaviour? Would it be possible to test the behaviour without the "chroot" statement? .marcoc
