[Lustre-discuss] BUG 5653 message in syslog

[Wojciech Turek]

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".
