我正在尝试使用paramiko sftp复制大文件(~650mb)文件.我能够复制小文件,但是当我尝试复制大文件时,我看到以下错误.我可以使用sftp直接从终端复制文件.

File "/usr/lib/python2.7/dist-packages/paramiko/packet.py", …我试图在应用程序处于后台时获取麦克风。我正在使用音频单元技术，并且能够在后台录制音频。但是一旦我的 AudioSession 被中断，我就无法在后台使用应用程序重新启动 AudioSession。注意：如果应用程序位于前台，我可以重新启动 AudioSession。下面是中断对应的代码：
- (void) beginInterruption {
[[AVAudioSession sharedInstance] setActive:NO error:&error];
AudioOutputUnitStop(m_audioUnit);
}
- (void) endInterruptionWithFlags:(NSUInteger) flags{
[[AVAudioSession sharedInstance] setActive:YES error:&error];
AudioOutputUnitStart(m_audioUnit);
}
AudioSession设置对应的代码
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryRecord error:&error];
[[AVAudioSession sharedInstance] setActive:YES error:&error];
AudioUnit对应的代码
// Describe audio component
AudioComponentDescription desc;
desc.componentType = kAudioUnitType_Output;
desc.componentSubType = kAudioUnitSubType_RemoteIO;
desc.componentFlags = 0;
desc.componentFlagsMask = 0;
desc.componentManufacturer = kAudioUnitManufacturer_Apple;
// Get component
AudioComponent inputComponent = AudioComponentFindNext(NULL, &desc);
// Get audio units
oserr = AudioComponentInstanceNew(inputComponent, &m_audioUnit);
checkStatus(oserr);
// Enable IO for recording
UInt32 flag …
