leak

I'm running PD10 for Mac v10.4.0 with Windows 7 as guest on an iMac 5k with 16gb of memory. Parallels is taking more memory every hour until ultimately it crashes. See images below for details, first is right after launch. Is this a bug? Any suggestions for a fix would be much appreciated...

In last version of Parallels Client I got strange memory leak: process used 41GB memory, swapped to 13GB with max memory in my iMac is 8GB. After 5-10 mins of brakes - macos is rebooted automatically. It's first and (I hope) last incident. But how it's possible? Screens:
