[#1]

I have consumer offset topics with 50 partitions and this is compacted topic with segment.bytes=104857600. Out of 50 partitions , for 5 partitions the old logs are not getting deleted. It is having the log files from the starting. 

Due to this the file system is getting full. can anyone know the solution for this?

We are using kafka 2.2.1 version
