MsDtsSrvr.exe memory leak?

In our current environment, we are running about 10,000 packages per day on a given 64 bit SSIS server.

The MSDtsSrvr.exe (SSIS service) process' memory working set size continues to grow until it consumes the memory on the machine.

Some of the packages do use a custom component. Could this be responsible for leaking memory in the MSDtsSrvr.exe process? Has a memory leak been confirmed in this process for the "first-party" components anyway?

More information about the possible memory leak.

The packages are run in in a CLR process with calls Package.Execute(), rather than being executed via dtexec or dtexecui or the designer. The reason for this approach is the ability to write a custom event handler with access to the package pointer, which other log handlers cannot do. The process runs Package.Execute() and exits, so there are 10,000 short-lived processes, each of which call Package.Execute() once.

To be slightly more specific about what the packages are doing, each of the 10,000 packages generally correlates to 1 source file, loading in dummy (aka inferred) dimension records, and then populating a fact table via a surrogate key pipeline.
