I've noticed recently an increase in the number of times motors cut out on the 92 stock because of people leaning against the doors when leaving stations.
Yesterday, the train jerked constantly until stopping completely, at which point the driver announced 'please stop leaning on the doors, this can cause a number of problems with the train'.
In the rush hour, sometimes it's difficult not to lean against the doors.
Are the doors becoming more prone to this problem as the trains get older?

I'm not aware of aging issues. I am aware of crowding issues!

The problem is that when the train accelerates, a backward force is exerted, which effectively means that there is less force holding the door closed. If people lean on it, the door opens easily (but only by a few inches). This is enough for the train to lose its pilot light, which causes the motors to cut out until the door is fully closed. The same problem occurs when the train is decelerating, but on the other door leaf.
It's quite amazing how easy it is to push open the 92TS doors. OK, they will only open a few inches, but compared to other stocks, it's very easy.
