Dear All, We are running 2.6.9-55.0.9.EL_lustre.1.6.3smp We can see in syslog of the OSS following messages. I tried to get access to this bug through bugzilla to get more information but I got message that my account is not authorized. Is there a patch for this bug? BTW I found following information in changes notes for lustre 1.4.2 # Severity: Major Frequency: Occasional Description: The fix for 4908 (in 1.4.1 RC1) was not quite complete, and could lead to a failed assertion requiring a reboot. (5653) I am not sure if this is the same bug but #bug number seem to fit. It worries me that it appears in 1.6.3 release as severity of that is "Major".
