> Key: IGNITE-3513
> URL: https://issues.apache.org/jira/browse/IGNITE-3513
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 1.6
> Reporter: Denis Magda
> Assignee: Semen Boikov
> Fix For: 1.7
>
>
> There is a bug in current implementation of
> {{GridCacheTtlManager#CleanupWorker}}.
> Refer to the implementation's code snippet and the details below.
> {code}
> EntryWrapper first = pendingEntries.firstx();
> if (first != null) {
> long waitTime = first.expireTime - U.currentTimeMillis();
> if (waitTime > 0)
> U.sleep(waitTime);
> }
> {code}
> 1. Put first item with TTL = 1 hour. CleanupWorker will go to sleep for 1
> hour.
> 2. Put second item with TTL = 1 minute. Since
> CleanupWorker's thread sleeps now, second item will not be expired at the
> time.
> NOTE: This scenario is easily to reproducible if first and second items are
> put into cache asynchronously. If try to put them in same thread one-by-one
> expiration may work fine.
