BI 4.1 SP6 - random instance failure
We have been seeing frequent instance failure after migrating reports from R3 to R4.
We have over 300 instances scheduled to run daily , everyday 10 to 15 random reports are failing.
On demand refresh works fine.
We have tried recreating job servers, still issue exists.
Our is cluster setup and we have 5 job servers running on each node.
Some of the common errors are
An internal error occurred while calling 'processDPCommandsEx' API. (Error: ERR_WIS_30270)
Object could not be scheduled within the specified time interval.
An internal error occurred while calling 'getSessionInfosEx' API. (Error: ERR_WIS_30270)
while trying to invoke the method com.sap.sl.parameter.DynamicValue.getUserFormula() of a null object loaded from local variable 'value'
An internal error occurred while calling 'openDocument' API. (Error: ERR_WIS_30270)
Any help is appreciated ?
