I have web server running Apache 1.3.23/FreeBSD. It serves requests to small plain text files residing on NFS. NFS server often updates files and web clients often download them. All forked fine for years until I updated web server to 4.6-PRERELEASE. Now web server sometimes fail to serve request due to SIGBUS in a child trying to read file. Apache was not updated, NFS server was not touched. NFS server is old FreeBSD 4.5-STABLE. I've recompiled Apache with CFLAGS="-O0 -g" and got coredump. One can have binary, coredump and untouched build directory at http://www.grosbein.pp.ru/apache/ Binary and coredump are compressed to httpd.debug.tar.bz2 Apache seem to fail trying to read mmap'ed file from NFS. Someone, please look at this. Eugene Grosbein To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
