iPrint spoolsv high CPU


We have a problem with our Windows 2008R2 RDS-servers where recently (Last 2 months) the spooler service starts eating CPU until the machine freezes.

We have Samsung/HP/Aficio printers and are using mainly Universal drivers for all three.
No driver updates was made at that time and we have tried updating after but no luck.

With Process Explorer I have been able to find out that it is the one or several of the thread "ntdll.dll!RtlValidateHeap+0x150" that starts using more and more CPU.
I have googled but not found anything concerning our problem.

Using iPrint client 6.02 (Had 5.98 when problem started so didn't help with that upgrade either)
