Hi all ,
I have been experiencing intermittent locking issues with MYSQL. It
appears that sometimes a query will lock reliease its lock, and is
causing other queries to wait and wait until the connection limit is
reached and i am locked out of the database. Has anyone ever had
anything like this happen?
The setup:
Redhat 9.0 , Kernel 2,4,20-8smp
mysql-standard-4.1.7-pc-linux-i686-icc-glibc23
MyISAM Tables (And unless InnoDB can support fulltext or some other
equivalent , migrating isnt an option at present)
ext2fs
Our Datbase Activity:
We have a somewhat active website.
Things run fairly smoothly for the most part , although we do have some
slow queries from time to time.
We have far more selects than updates , but updates are still reasonably
active.
Frequently , an update will get locked while a slower query is running.
Sometimes we can experience a large backup waiting for a slow query ,
but typically everything sorts out once the slow query finishes.
Rarely , however , a query will be in a "locked" state and will not let
go of its lock. Subsequent updates lock , and subsequent selects lock.
Eventually , if the above has happened , the connection table will fill up.
We dont have any scripts that explicitly LOCK TABLES , aside from our
backup script which uses mysqlhotcopy.
Is it possible that the mysqlhotcopy LOCK TABLES could interfere with
the locking from the website activity?
I apologise for the vagueness of this request , I really dont know what
direction would be best to further diagnose this.
If you have any advice , it would be greatly appreciated.
thanks for your time!
Aaron
