DM8168 DVRRDK3.5 几率性出现进程挂起、休眠问题，鼠标停止不动

大家好：

         我在用dvrrdk3.5开发包时几率性出现进程挂起、休眠问题，现象是鼠标卡住不动，整个QT界面卡死不动，16路OSD卡住不动，日期时间等不再更新，但16路预览正常，说明dsp和m3没死，只是arm端的某些进程被挂起、休眠了，复现没有抓住规律，有时刚启机，有时正在操作某些界面。问题出现时还可以telnet，用top -d 1 命令后发现剩余内存100MB左右，应该不是内存耗尽问题，还发现cpu占用率为0。

         出现此问题时底层有如下打印：

          .......................

           [host]  IPC_BITSINLINK:!WARNING!.Commands not being processed by link.TimeSinceLastAlloc:176,TimeSinceLastFree:176

           [host]  IPC_BITSINLINK:!WARNING!.Commands not being processed by link.TimeSinceLastAlloc:192,TimeSinceLastFree:192

           [host]  IPC_BITSINLINK:!WARNING!.Commands not being processed by link.TimeSinceLastAlloc:208,TimeSinceLastFree:208

           [host]  IPC_BITSINLINK:!WARNING!.Commands not being processed by link.TimeSinceLastAlloc:224,TimeSinceLastFree:224

     请问大家有谁遇到过类似问题？请指点一下或给个建议，谢谢！
