已崩溃：queue.SJMediaCacheServer EXC_BAD_ACCESS KERN_INVALID_ADDRESS

[kaifuZzz]

使用如下方法进行批量prefetch的时候，会出现偶现的crash
`- (void)prefetchVideos
{
NSArray <NSString *>*videoUrl = [self videoSourceUrlStrings];
if (IS_ARRAY_EMPTY(videoUrl)) return;
//缓存开始
[SJMediaCacheServer shared].maxConcurrentPrefetchCount = 10;
[videoUrl enumerateObjectsUsingBlock:^(NSString *obj, NSUInteger idx, BOOL * _Nonnull stop) {
NSURL *storeUrl = [NSURL URLWithString:obj];
[[SJMediaCacheServer shared] prefetchWithURL:storeUrl progress:^(float progress) {
} completed:^(NSError * _Nullable error) {
NSLog(@"缓存结束");
}];
}];
}

• (NSArray <NSString *> *)videoSourceUrlStrings
  {
  if (IS_ARRAY_EMPTY(self.videoList.records)) return @[];
  return [self.videoList.records valueForKey:@"videoUrl"];
  }
  `

crash的堆栈打印信息如下
