I'm thinking it has to do with the threading modes handled by the bsd kernel: libkse, libc_r, libthr. If say apache was compiled with libkse and php with libc_r, this is the kind of threading conflict i think could occure. > Any clues people might have as to the cause of this problem would be > gratefully received. > > FYI: OS is FreeBSD v5.2 and Apache if v2.0.55 If you are doing this on a cvsup'd port, there could have been major changes, you are using the portupgrade tool to install these ports right? I would search the bsd-ports or bsd-general mailing lists to see if this there is anything related, and also you could try the bsd specific google search: http://google.com/bsd HTH, Curt. -- cat .signature: No such file or directory
