May be this is relate to #499.So close this for now I will do a update to check.

@lizouzt Have you fixed it somehow?

@pkantsedalov
Down there fixed some of this crash. But i've remember it's should be published on V.0.10.9, not sure.

RNFetchBlobNetwork.m

- (id)init {
    self = [super init];
    if(taskQueue == nil) {
        /***************** those two *****************/
        // taskQueue = [[NSOperationQueue alloc] init];
        // taskQueue.maxConcurrentOperationCount = 10;
        /****************** change to ****************/
        @synchronized ([RNFetchBlobNetwork class]) {
            if (taskQueue == nil) {
                taskQueue = [[NSOperationQueue alloc] init];
                taskQueue.maxConcurrentOperationCount = 10;
            }
        }
    }
    return self;
}

@lizouzt Thank you for the snippet.
Have you already used V.0.10.9? I see that it's a tag, not yet an official version, so a bit afraid of its usage.
