> {noformat}
> org.apache.ignite.spi.IgniteSpiOperationTimeoutHelper#nextTimeoutChunk
> long curTs = U.currentTimeMillis();
> timeout = timeout - (curTs - lastOperStartTs);
> {noformat}
> Timeout will not be decreased at all if delay between successive calls to
> nextTimeoutChunk() is smaller than U.currentTimeMillis() discretization. Such
> behaviour could be easily achieved when getting an error right after the
> nextTimeoutChunk() invocation and do the retry.
> Only rare calls (the first right before U.currentTimeMillis() and the second
> right after that) may decrease timeout, so actual
> IgniteSpiOperationTimeoutHelper timeout could be much bigger than the
> failureDetectionTimeout.
> My opinion to not split failureDetectionTimeout between network operations,
> but initialize first operation timestamp at first call to nextTimeoutChunk(),
> and then calculate the timeout as a difference between the current timestamp
> and the first operation timestamp.
