Chkrootkit 0.46 Problem

Cordeiro posted the following message on the FreeBSD security list. I didn't test it (I don't have testing server).

...don't use chkrootkit 0.46 on production machines. The "chkproc" process sends a SIGXFSZ (25) signal to init, that interprets this signal as a "disaster" and reboots after a 30s sleep.

I tested chkrootkit(0.45) and Rootkit Hunter before. I prefer Rootkit Hunter.

MySQL Log File

I didn't know MySQL log file until I tried to clean up unused databases today, the default file path is /var/db/mysql/hostname.err.

In my log file, there are many error messages about one certain table, the error is like:
read_next: Got error 127 when reading table ./database_name/table_name

MySQL tried to repair the table many times according to the log message, but the problem still exists. Made a quick search, it might be a bug of MySQL 4.0, some pages said it could be fixed by repairing the table, which didn't work for me.

Repair table with MySQL command line:
mysql> repair table table_name;
