码流配置情况如下：
“venc1” : {
“bitrate” : 4000,
“fr” : 25,
“h” : 1440,
“name” : “H264_CBR”,
“svc_enable” : 0,
“w” : 2560
}
vi的配置：
“sensor1” : {
“lane_mode” : 0,
“max_h” : 1440,
“max_w” : 2560,
“name” : “SC4336P”
}

问题复现的方式：利用vlc或者onvif device manager打开实时画面，然后用手捂住摄像头，画面出现雪花状，就很容易出现程序被kill掉，大概20%的概率。请帮助尽快解决，看看是不是内存分配或者isp配置的问题？
下面是出现该情况时，打印的日志：
