we are using cognos 10.2.1 ,we have 4 dispachers  2 gateways and one content manager running in the environment(one dispatcher act like stand by content manager)

when we raised the issue with IBM they have given some fix for the web apps for delivery services and asked us to set the delivery services to false on all the dispatchers  and set to true only on the content manager

it was working fine for 3 months and causing this issue again IBM stopped supporting the 10.2.1 version anymore

if we do the NC table drop then the job is running fine for the first time and second time throwing an error

please suggest if any solution for the issue
