The syscalld timeout mechanism might cause premature logging of OPERATION_TIMEOUT messages.


The system posts the message: syscalld[21190]: 0127000a:3: OPERATION_TIMEOUT 'command' may be hung or taking a long time. This may cause some operations, such as establishing CMI trust, to fail and need to be launched again.


No specific configuration is required.



Fix Information

syscalld's timeout mechanism no longer emits an OPERATION_TIMEOUT message, unless the message appropriately reflects the condition of the system.
