Hi, I'm currently running FreeBSD 4.3-stable with MySQL 3.23.39. My problem is weird an unpreditable. I have a database driven website which has several hundred visitors per day. After viewing my logs on a daily basis, I see a "Unknown database" error appear from time to time. Now, I also have a script set in cron which accesses the database every so often an I see the same "Unknown database" error from time to time when this script is ran. The error is completely spuradic and unpredictable. Sometimes I go for days without seeing the problem. Not only that, if I notice the problem immediately and check things out, I can connect to the database. So within a matter of minutes it goes from an Unknown database to a database that is alive and accessible.
I've tried upping the "mbufs", checking the "file descriptors", "tweaking the mysqld server params", applying "soft-updates", and "turning off Apache::DBI", nothing seems to work. I've seen at least 2 other mailing list entries where people have the exact same problem. The only solution I received was to switch to a Linux OS. I've also read that there is a threading problem with FreeBSD+MySQL on an SMP machine. I'm running a machine with only 1 processor. Do you have any idea as to what may be causing this problem and if so, do you have a suggested solution? Any help you may be able to give will certainly be appreciated.
