Crash cased by 0xdead10cc exception
I know that it seems that crash was caused by thread 0 from the crash reports (attached) but from what I see this code 0xdead10cc refers to holding file lock too long and in both crashes its DDLog that locking the file.

Describe the bug App crashes when its in the background and tries to log to file.
To Reproduce
NSFileManager* fileManager = [NSFileManager defaultManager];
NSURL* containerUrl = [fileManager containerURLForSecurityApplicationGroupIdentifier:@"group.com.cherpake.macrc"];
NSString* logsDirectory = [[containerUrl path] stringByAppendingPathComponent:@"AppLogs"];
// Create this folder in case it doesn't exists
[fileManager createDirectoryAtPath:logsDirectory withIntermediateDirectories:YES attributes:nil error:nil];
id<DDLogFileManager> logFileManager = [[DDLogFileManagerDefault alloc] initWithLogsDirectory:logsDirectory];
_fileLogger = [[DDFileLogger alloc] initWithLogFileManager:logFileManager];
_fileLogger.maximumFileSize = (5 * 1024 * 1024); // 1MB KByte
_fileLogger.logFileManager.maximumNumberOfLogFiles = 3;
[DDLog addLogger:_fileLogger];
then create a thread that runs in the background and logs to file
Expected behavior Shouldn't crash
