Hi, I downloaded and compiled mysql 4.0.9 gamma this morning, and still get the same error. This doesn't seem to be related to reverse DNS. I've got the crash from both types of client hosts (with and without reverse).
The official 4.0.9 binary version seems to work well. What did I miss ? My config is: - HP LH4 server (dual PIII 700 MHz, 1GB RAM, 12 GB MegaRAID HD) - RedHat Linux 8.0 (kernel 2.4.18) - Compiler: gcc 3.2 20020903 (Red Hat Linux 8.0 3.2-7) - configure options: ./configure --prefix=/usr/local/mysql --enable-assembler --with-mysqld-user=mysql --with-openssl Best regards, Mark Matthews wrote: >Christopher E.
