Thanks for helping me out! It's not very informative ;-) According to previous ldd output, apache2 doesn't call libc_r of any thread lib. "ldd /usr/local/libexec/apache2/libphp4.so" should help us to know if it comes from here. can you send me your modules list too ? FYI, I run IMP-4.0-cvs on apache 2.0.50 (prefork) + php 4.3.7 without any problems. clem --Signature=_Fri__16_Jul_2004_11_15_15_+0200_FIy7vqAhs1e3frB9 Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (FreeBSD) iD8DBQFA95yosRhfjwcjuh0RAoVtAKCymgtSY4XHODOgQOWkbODpdnzi5QCghmk8 21JjDG2k9VnTw8+3GDWakGU= =OgWh -----END PGP SIGNATURE----- --Signature=_Fri__16_Jul_2004_11_15_15_+0200_FIy7vqAhs1e3frB9--
