Hi, What you are experiencing is not actually caused by our code. The files that you are listing are all temporary files. Linux is unique in handling temporary files, because it has a very nice feature named "pool of temporary files". We use that feature, for the performance purposes, so that entire handling of temporary files is left to the OS. I guess that this feature can be tuned in the OS, so this is something that your sysadmin should be able to solve. Regarding running out of the memory, it has to do with how you have configured your MySQL server and can not be a bug.
