Hi Aurigma,

We have discovered a memory leak somewhere inside of Graphics Mill. We tracked it down using Debug Diagnostics and dumping memory after monitoring for a leak for 1 hour. In that one hour, we had a leak of 36MB.

Here's information from the DebugDiag report. (I emailed the report to Dimitri)

WARNING - DebugDiag was not able to locate debug symbols for Aurigma.GraphicsMill.DLL, so the reported function name(s) may not be accurate.

Aurigma.GraphicsMill.DLL is responsible for 36.98 MBytes worth of outstanding allocations. The following are the top 2 memory consuming functions:

Aurigma_GraphicsMill+12b50a: 36.63 MBytes worth of outstanding allocations.Aurigma_GraphicsMill+9a3ce: 353.22 KBytes worth of outstanding allocations.

Here's a sample method call for that instruction

Function Source Destination

Aurigma_GraphicsMill+9a3ce ole32!CoTaskMemAlloc

We'd like to look at it closer, but we need Graphic Mills' 4.5.23 PDBs to examine the actual calls.

This is causing us to reboot production servers nightly. This is a high priority for us.

Thx, Joel
