Win32NetBIOS lead to 100%CPU usage?

[alvisccc]

Hello,

My Alfresco is alfresco community 3.2r,it runs under windows server 2008 64 bit with 6 G memory.
I have inserted 2 million records into alfresco in many days.During the inserting process if the alfresco is running about 20 hours,
the cpu usage of JVM will jump to 100% and didn't drop even suspended the inserting process.The computer will become very slow.

I have been using HotThread or jstack to trace what happen inside.It show the following :

It may be the Win32NetBIOS problem.
I search a bit,suggested to copying Win32NetBIOS.dll,Win32NetBIOSx64.dll,Win32Utils.dll,Win32Utilsx64.dll in C:\alfresco\bin
to C:\windows\system32 directory.But it doesn't help. Are there any solution on this,Please help?

thanks

Please configure your smb(File server subsystem).http://wiki.alfresco.com/wiki/File_Server_Subsystem

Can i disable smb alfresco server,by typing cifs.enabled=false in file-server.properties file .It's that correct ?

[sfreeper]

this should be correct.

Hi,

I am also facing the same issue , indexing  increases and  cpu utilization goes to 100%.

How did you solve the issue.

Thanks,
Amita
