Hi,
I have a strange issue with new backing indices creates after rollover. Suffix number is incrementing by two numbers instead of one.
Initially, ILM generated new indices with correct names incrementing only one number, but now it increments two numbers.
Here are the logs:

Any reason for this situation? Is this a bug?
Thanks.
