I posted this over in the transcoder forum, because I figure it has something to do with that, however, it may just be a normal thing.
thread over in the other forum is
This sever (3.6.2, windows, 16 cores, 24GB ram with 8000M heap size) is running four live streams with little traffic. Two are single bitrate, two are transcoded from 720p to 360p, 240p and 160p. Starting up the server and transcoders has the system running at about 750MB to 1000MB of RAM in use. Since the transcoder mountpoints were started, the amount of memory Wowza is using has been steadily creeping up. Today, 6 days later, we are averaging 2.8GB of RAM, and the trend is a pretty linear line upwards.
Is this growth in memory use normal? I am worried we’ll run out of memory after a few weeks when it hits the 8GB allocated for java.
server has “Java HotSpot™ 64-Bit Server VM version 23.0-b21”, threads are around 900, CPU runs around 25% when transcoding two sources.
