Description

Currently the catch is outside the while loop:

      try {
        while (cacheEnabled && writerEnabled) {
...
      } catch (Throwable t) {
        LOG.warn("Failed doing drain", t);
      }

When exception (e.g. BucketAllocatorException) is thrown, run() method would terminate, silently.
