> Sometimes when a cache is stopped and its corresponding {{GridCacheContext}} is cleaned
up there are some threads exist that keep executing cache related operations.
> This may lead to deadlocks, hangs and other unpredictable results.
> Initial discussion on the dev list:
> http://mail-archives.apache.org/mod_mbox/incubator-ignite-dev/201508.mbox/browser
> Look for discussion "Fixed deadlock in GridDhtAtomicCache (Alex G. your review is needed)"
> As an example, the bug described and fixed as IGNITE-1189 was caused by already invalidated
{{GridCacheContext}}.
> Moreover, Andrey Gura reports that he observes hangs in cache's read operations probably
caused by the same reason.
> To reproduce try to do the following.
> Temporary comment out the following catch block in {{GridDhtAtomicCache.updateAllAsyncInternal0}}:
> {noformat}
>         catch (Exception e) {
>             // At least RuntimeException can be thrown by the code above when GridCacheContext
is cleaned and there is
>             // an attempt to use cleaned resources.
>             U.error(log, "Unexpected exception during cache update", e);
>             res.addFailedKeys(keys, e);
>             completionCb.apply(req, res);
>             return;
>         }
> {noformat}
> Run {{IgniteCacheAtomicNodeRestartTest.testRestartWithPutTenNodesTwoBackups}} in a loop
using TeamCity.
