NIM thread blocked errors coming from root 1

[billy1]

Hi,


I am getting the following from root in our AIX 5.2 box. Should I be worried about this.

IDENTIFIER TIMESTAMP T C RESOURCE_NAME DESCRIPTION

I checked vmstat.

I checked topas for cpu usage, but it seemed fine.

Thanks for you help

Hi

I never had this message but have a look to the following thread:

http://www.tek-tips.com/viewthread.cfm?qid=1240662&page=1

http://www.tek-tips.com/viewthread.cfm?qid=1193792&page=10

You can check also if you have pb with a cable connection.

Here the code info: for 864D2CE3
TS_NIM_ERROR_STUCK_ER

864D2CE3
PERM Explanation: One of the threads in a Network Interface Module (NIM) process was blocked.

Details: This entry indicates that a thread in one of the NIM processes did not make progress and was possibly blocked for a period of time. Depending on which of the threads was blocked and for how long, the adapter corresponding to the NIM process may erroneously be considered down.

The standard fields indicate that the NIM was blocked and present possible causes and actions to prevent the problem from recurring. The problem may have been caused by a resource shortage at the node, or possibly excessive I/O activity.

The Detail Data shows the name of the thread which was blocked, the interval in seconds during which the thread was blocked, and the interface name associated with this instance of the NIM.

If there is no false adapter down event caused by the blockage, no action is needed. If there is, the cause for the blockage needs to be understood. To investigate the problem, follow the same steps as those taken to investigate the error entry TS_LATEHB_PE on page ***.

Sorry I am not helpful...

Good luck.
Cheers

I have seen these errors before, you must be on power4 Processor, Its common to have these errors, specially if you have HACMP in there too.
Nothing to worry about it, I too worried about it a lot but my search and conclusion ended on
1)Check the baud rate if you have HACMP environment
2)Your processor is not stromg enough, move up power5.
