Hello,
We've been getting random crashes on our MySQL servers running MyISAM
tables for the last month, its gotten very bad in the last two weeks.
This has occurred on both 5.0.27, 5.1.11 and 5.1.15-nightly20070103.
It crashes the tables with high queries per second. We've fixed the
issue on one of the servers by changing its tables to InnoDB. We can't
do that however on another server, which we turned debugging on
instead. It appears to be an assertion failure, the error message from
the MySQL debugging code is:
Assertion failed: fixed == 1, file item.h, line 1601
Any help is greatly appreciated. Should we report this as a bug?
Any crashing is most certainly a bug, so if you could gather as much
information on this as possible and report a bug that would be great.
Please include:
o The full section of the error log for the time of the crash
o If there is a stacktrace reported, the resolved trace following:
o http://dev.mysql.com/doc/refman/5.0/en/using-stack-trace.html
o If you could turn on core files and upload the core file, and mysqld
binary used to create it, as tar.gz to:
o ftp://ftp.mysql.com/pub/mysql/upload
o Link this in the bug report as well
Do you have any way to reproduce this as yet?
Cheers,
Mark
