You're removing one by one and each remove is synchronous distributed operation, so this is going to be very slow. You should use batching or even IgniteDataStreamer for this. BTW, maybe you can utilize automatic expiration [1] for this?
As for jammed cluster, this is weird. The first thing to check is memory consumption - are you running out of heap?
