Narrative:
An A321 aircraft had an MEL for a disconnected idg that was applied in november 2013. About an hour into flight; while doing standard ECAM check; we noticed that the idg on the electric page was pulsing due to a high temp 140 C and climbing. [We] contacted maintenance control thru dispatch; using onboard phone. Was instructed to disconnect idg again and the temperature started to drop after peaking at 155 C. Somehow the idg got reconnected in ZZZ
