<DIV><FONT color=#000080></FONT> </DIV>
<DIV><FONT color=#000080>Thank you for your advice!</FONT></DIV>
<DIV><FONT color=#000080>I wonder that the lustre error is a bug for version
1.6.6 or not. We plan to upgrade the server to 1.8.1.1, Does the bug fix?
And I still don't know why so many ldlm processes exsit in server, is it normal?
Can someone give me more details about this? Thanks a lot!</FONT></DIV>

<DIV>> we can see many processes about ldlm, it's up to hundreds. As a</DIV>

<DIV></DIV>
<DIV>We experienced the same with 1.8.1 servers and 1.8.0.1 clients.</DIV>
<DIV>Two weeks ago we upgraded the servers (2 MDS, 5 OSS) to 1.8.1.1 and</DIV>
<DIV>haven't seen this behaviour since.</DIV>
