[Maria-discuss] MariaDB 5.3 on lenny crashing about every 8 minutes
by Carsten Bernhard 02 Aug '11

Hi, I have installed MariaDB 5.3 from the apt packages on a lenny amd64 machine. Initial setup went fine and the database is working correctly. When I give some load to the machine I get crashes about every 8 minutes. This is what the log shows: Jul 29 00:36:17 svn mysqld: 110729 0:36:17 [ERROR] mysqld got signal 11 ; Jul 29 00:36:17 svn mysqld: This could be because you hit a bug. It is also poss ible that this binary Jul 29 00:36:17 svn mysqld: or one of the libraries it was linked against is cor rupt, improperly built,Jul 29 00:36:17 svn mysqld: or misconfigured. This error can also be caused by m alfunctioning hardware. Jul 29 00:36:17 svn mysqld: We will try our best to scrape up some info that will hopefully help diagnose Jul 29 00:36:17 svn mysqld: the problem, but since we have already crashed, some thing is definitely wrongJul 29 00:36:17 svn mysqld: and this may fail.

[Maria-discuss] Help with RPM src build
by bwellsnc 22 Jul '11

22 Jul '11

I have gone over every document concerning building mariadb using src rpm. I am trying to build mariadb against RHEL 6. I have run rpmbuild against the src rpm and I get this error everytime: error: configure: error: C compiler cannot create executables The instructions, I have to admit, are not very good about building using the source rpm. If there is anyone who has a better howto, I would really appreciate it. Thanks! Brent
