i experienced this when the BTS from the other operator went down during the night (due to maintenance, swap, etc…).
All MS from the other operator reselects my operator at the same time, resulting in extreme high congestion.

Are your cells located at country border ?
Check if those SDCCH requests are trying to perform location update, or IMSI detach, or MO call, SMS ?…?
