Hi,dearlist
We got a high frequency of logining node crash these days. The scene is that we can't remote access to the nodes but we can access them in the terminal. We run the command :
ps -ef |grep ldlm
root 3823 1 0 10:57 ? 00:00:00 [ldlm_bl_00]

we can see many processes about ldlm, it's up to hundreds. As a result, the load avarage is too high (155.0 165.0 145.0) to work normally.However, we have no idea and have to restart the nodes. At the same time,we can get the log as follows:
The filesystem features:
Server: lustre 1.6.6
Client: lustre 1.6.5
Can someone else get the same problem?
I will appreciate for your any help!
