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:

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!

有没有测试过单通道视频处理,会不会也出现这样的问题呢 ?
在DVRRDK3.0 中是否有同样的问题 ?
