DM385 A8接收码流线程IpcBitsInLink_periodicTaskFxn（mcfw/src_linux/links/ipcbitsin/ipcBitsInLink_tsk.c ）理论上每隔8毫秒去轮询一次通知其他线程去接收从片数据，但设备运行十来分钟后某一时刻会出现睡眠3秒多才返回，导致从片编码队列满视频丢帧。典型错误打印如下

同时我把该优先级提到最大都无济于事，每次出错必然是该线程中OSA_getCurTimeInMsec()函数会阻塞3000多毫秒（理论应该是IPC_BITS_IN_PROCESS_PERIOD_MS = 8毫秒）
同一套SDK同一个应用在DM8127平台上则不会出现以上打印信息。
能否帮我分析一下是什么原因引起上述问题？
执行DEMO同样会出现上述问题（./bin/ipnc_rdk_mcfw.out TRISTREAM TRIPLE_H264 APPRO2A AEWB 3MP_D1 HIGH_SPEED1 HIGH_SPEED2 MJPEG 80 &）
