Thanks Gowrishankar,
I also checked it in administrator perspective i can see below error in that
exception 40182:
repository/base/activation/activator.cpp:171
Repository activation lock timeout; another activation is still running; try again later
for past two days if it is running for long time i used to close the window after cancelling the validation job.. i am suspecting those old jobs are still running in background and is it because of those unfinished job?.. is there a way to see those jobs and clear it..
Thanks,
Rithika
