Hi,

in this knldia20100712.txt have the full knldiag the error is at line 10975 on 2010-07-12 16:43:57.

i just restarted the system and all comes back again, but there is a way to check, predict or avoid this to occurs again?

best regards

HI Clovis,

looks like this : http://maxdb.sap.com/webpts?wptsdetail=yes&ErrorType=0&ErrorID=1138883

If this would be mine DB, I'd install the current available patch, run the parameter checker (and correct the settings) and see if the issue reoccurs (shouldn't).

regards,

Hi Lars,

if i understand you mean that in some internal user function, one of these errors:

-4005: Unknown column name

-8006: Data types must be compatible

occurred, causing the system crash, right?

what i dont understand is what you mean with "and correct the settings", you see any wrong settings in my knldiag, that can cause this problem?

regards

The kernel crashes here:

This seems to be an issue with the thread library.

You're using a pretty old version:

VERSION 'Kernel 7.6.03 Build 007-123-157-515'

I'd update to the latest build (7.6.6.x) available.

What exact operating system and patch level is that system?
