http://nagoya.apache.org/bugzilla/show_bug.cgi?id=11514 MPM of worker leads to Apache stalling (child exits) ------- Additional Comments From [EMAIL PROTECTED] 2002-10-08 00:17 ------- I was asked if a core dump were available. It is not at this moment, but I can add to the observations. I rebuilt Apache with version 2.0.40 using the following script file: # more myway.thread #! /bin/sh ./configure \ --prefix=/opt/lib/httpd2 \ --enable-http \ --enable-auth-anon \ --enable-mime-magic \ --enable-cern-meta \ --enable-expires \ --enable-headers \ --enable-unique-id \ --enable-ssl \ --enable-dav \ --enable-info \ --enable-cgi \ --enable-dav-fs \ --enable-speling \ --enable-rewrite \ --enable-so \ --enable-modules-shared=all \ --with-ssl=/usr/local/ssl \ --with-mpm=worker ------------- This build worked much better than 2.0.39. However, it has two major problems of the kind discussed in the original report. First, asking for /server-stats/ causes the server to cease serving, with no error messages. Using apachectl stop yields errors about unable to do thread_join, which suggests a thread is lost. Second, I let this run overnight in production mode. Alas, it stopped rather soon thereafter and wedged in the same way as above. Yet I could test the server with zb and ab and it performed fine. So there is some combination of requests which cause thread problems. I infer these two difficulties are related in some manner, and tied to those initially reported for v2.0.39. 2.0.40 is better (server does get to the working state). The server does not crash in the formal sense, it just ceases to progress and does not respond. Building is with the stock UnixWare C compiler, not with gcc. No problems noted. If I remove with --with-mpm=worker line the resulting pre-forked server runs perfectly. Stock mpm settings in httpd.conf.
