> Even with write throttling enabled, checkpoint buffer still can be overflowed. Overflow chance increases with number of writing threads. Example stacktrace:
> {noformat}

> The problem is that we apply throttling by checkpoint buffer only for pages that are present in current checkpoint:
> {noformat}
> if (isPageInCheckpoint) {
> int checkpointBufLimit = pageMemory.checkpointBufferPagesSize() * 2 / 3;
> shouldThrottle = pageMemory.checkpointBufferPagesCount() > checkpointBufLimit;
> }{noformat}
> On the other hand, we clear backoff counter if we don't apply throttling, which can happen for page which is not in checkpoint:
> {noformat}
> if (shouldThrottle) {
> int throttleLevel = exponentialBackoffCntr.getAndIncrement();
> LockSupport.parkNanos((long)(STARTING_THROTTLE_NANOS * Math.pow(BACKOFF_RATIO, throttleLevel)));
> }
> else
> exponentialBackoffCntr.set(0);{noformat}
> Possible solution: introduce two separate backoff counters for pages in / not in checkpoint.
