I have a Server with 2 Xeon E5645 total 12cores and 24 threads on a X8DAH+-F-B Motherboard and 96Gigs of Memory and 4 Terabytes of hard drive space. We are running the newest stable release of MariaDB 5.5.25. every night I run a PHP script to bring a large data set roughly 500K records or so into a XtraDB Table I use as a "SWAP" table. I processing,filtering, massaging the data in this table then insert this processed data into other tables where it can be accessed by a web application. At the end of this Script I DROP this "SWAP" table. This Script runs 24 times a day and does not seem to have much issues. But For Some reason seemingly randomly the DROP table Command while checking permissions to drop the Table will lockup the database. I have tried truncate too and it seems to have the same issue. The innodb_buffer_pool_size=35G. Any Ideas what the problem could be or where to start looking?
