multiple conhost.exe are running on my Windows Server 2008

• O/S: Windows Server 2008 R2 64 bits
• Oracle RAC Database: Oracle 11.2.0.2
• 02 nodes: NodeA and NodeB.

On NodeA, I have succesfully applied patch p12714463_112020_MSWINx 86-64, which solved the daily growing number of cmd.exe services.

However, there are at least 25 conhost.exe running ( I see all of them at my Windows Task Manager) like:

conhost.exe SYSTEM 00 2,892 K \\??\C:\Windows\system32\conhost.exe
conhost.exe SYSTEM 00 2,916 K \\??\C:\Windows\system32\conhost.exe

Is it normal behavior in an Oracle RAC server? Received on Fri May 25 2012 - 16:14:25 CDT
