I didn’t thought I would have to come back on this installation. But here we are with Part 3 !!
If you tried to compile on Solaris and stream for more than 200 users, you experienced a crash. I thought the trick from part 2 was solving this, as my production server was running fine on more than 1000 users (test only

While I was documenting the install process, I was also deploying new servers, with fresh compile and install. And I found that the menly compiled server was crashing at 200+ streams !!!!

DAMN !

Going back to my “working” compile, trying to diff between original source and patched one, I just found that I changed something else.
There is a small (ugly ?) function somewhere which tries to detemine how many CPU the server have. On solaris this function seems to start a “uname -X” for each incoming user !

My patch was to comment out all this and have this function return a static number (I don’t know why I set it to 24 :))

For those of you needing it, here is the patch (in diff -u format) :

Set the number of CPU to whatever you wish, 2 or 8 may be a good number. This number can be set in the config file, using the “5” parameter.

I think that’s it, you have everything you need now

Let start streaming !
