Missing Java Runtime 1.4. Unable to create JVM
Hi Folks,

got a stabile 7.0.23 release of Sage running on Windows Home Server.

The SageTV service is working; whenever I reboot my machine, I get a 'reinstall Java 1.4 (JRE) message' on the Control Panel software.

I have version 1.6 of Java on the machine which is correctly installed.

Why am I getting this message; occasionally, once every 2-3 weeks the SageTV service crashes and has to be restarted; not sure if these two issues are related.

Any advice appreciated!

Look to see if you have an older version of java installed. On the older versions, when you installed a newer version it didn't uninstall the old version. Go into Control Panel and uninstall all versions of java except for the latest one you installed. And the WHS version already comes with java in the jre folder of SageTV on WHS. Technically you don't have to install java on WHS.

Make sure Sage is not running (i.e. the service is stopped) whenever you uninstall or upgrade Java.

I woke up this morning to this problem. I've never seen it before. I tried reinstalling java. I removed all versions of java. I even ran a tool called javara that removes old versions. I installed the latest JRE from sun But I keep getting this error and can't get Sagetv to run at all. Any ideas? I've been running sage for months without serious problems and now this all of a sudden. I didnt change anything.

Any help?

Fixed my problem...

I don't know why this happened this morning but I discovered by searching online that if you set your JVM heap size too large it can fail to create the JVM. I forgot that I had been getting out of memory errors so I experimented with larger and larger heap sizes to see if it would resolve the problem (it didn't but I think that has to do with some plugins). I had the heap size at 800. Reduced it back to 200 and restarted the computer and all is working it fine now..

I had the heap at 800 for the last week or so and didn't have this problem until now.. no idea why it only happened this morning but thankfully was an easy fix.

+ 1.

For me, 400h (max) was failing.

Dropped it to 399h and the problem went away.
