Universal Media Server | Forum

One question i have is, "Since java is such a memory and resource hog, why use it? like seriously? Why not C# or ajax?" Why does anyone use java at all anymore? it's like Minecraft all over again. Unles you use "this" gpu or "this" os or have more than "this" amount of memory, your system will fail. That's why it's virtually flawless on xbox 360 is because it isn't a java platform game. I digress...

i bring this up because i noticed also with older versions, that UMS will start to "act up" after a while. video starts to skip or lag or stop all together. it's doing that now. oh, and it is working, unless you haven't surmised this by now; but not without it's problems

If you see two javaw.exe processes it is wrong. UMS wasn't quit correctly so it was started second time what is bad situation because when there are two UMS processes, UMS doesn't work correctly or at all.
About UMS that is programmed in JAVA. JAVA is multiplatform and Shagrath, the founder of this UMS/PMS application programmed it in language which he understood so because JAVA
About 600MB in memory. Do you think application in C++ or in .NET, C# etc. will not use so much?
Java code itself is quite small but UMS uses buffer which have to be allocated in memory. When you browse folders, all thumbs and media info is stored in memory, all your web.conf list is stored in memory, all plugin data are stored in memory so when you browse same folder again, UMS can immediately show needed data without any repeated (slow) resolving. Browsing movies with MovieInfo plugin which gathers info from web page, all is stored in memory so next time same info is displayed directly from memory instead of slow retrieval from web again. Your buffer settings allocates your memory so using 400MB buffer will allocate same amount, but for one renderer! More renderers, more memory (every renderer uses own buffer)
So 600MB used? My UMS after week of running can use between 400 to 1600MB depending on the action in progress (when transcoding is active, more memory is allocated)
There is no reason to complain on Java

Your renderer is Panasonic TV. You changed max bitrate from 110 to 0=unlimited.
This change is irrelevant in your case because renderer.conf itself uses "MaxVideoBitrateMbps=90" because it has crappy 100Mbit and can't use more than 70Mbit for longer time (bitrate about 70Mbit for ten of seconds =stuttering...)
Your uploaded log is empty. You started UMS, switched logging to TRACE and generated logs without playing anything. Try to lower max bitrate to about 70 and test again, make logs, upload them. If file is transcoded it is possible it generates bigger bitrate than your network connection/TV can accept. 70Mbit should be OK fro wired connection, 15Mbit for WIFI in most cases (your network card is 1Gbit so try using value 70)

THank you ExSport... well put.
