jrun

We are running JRun 4 and have lots of crashes. I am trying to understand where the problems are coming from and have modified the jrun.xml file to enable metrics logging.

This is what I'm seeing...

01/06 15:07:27 metrics Web threads (busy/total/delayed): 2/100/0 Sessions: 0 Total Memory=70720 Free=7464
01/06 15:08:27 metrics Web threads (busy/total/delayed): 1/100/0 Sessions: 0 Total Memory=66944 Free=9199
01/06 15:09:27 metrics Web threads (busy/total/delayed): 3/100/0 Sessions: 0 Total Memory=67456 Free=9644
01/06 15:10:27 metrics Web threads (busy/total/delayed): 3/100/0 Sessions: 0 Total Memory=63360 Free=8368

The book I've been reading (Adobe Coldfusion Anthology, Apress) suggests the "busy" number is the free memory in MB. The Adobe documentation says it's "Threads currently running". Which is correct?

Also, what does all this mean?

If I'm reading it correctly, I have 100 total threads, and 3 busy ones. So what are the other 97 threads doing if they are neither busy nor delayed?
