[mapguide-users] mgserver consumes about 100 % of processor capacity

I'm having trouble following what you did.
- "have transferred a folder"
=> are you saying you made a copy of the installation folder
containing mgserver?
=> why not just modify the mgserver.sh file in the original installed
location? Less
risk of making matters worse.
- Why do you get a stopped message in GDB?
=> Did you press Ctrl-C? If so, then enter 'bt' to get the trace.
=> If you run the copied mgserver without GDB does it hang (like the
original mgserver)
or does it show the "stopped" message? If you get the stopped
message then something
is messed up with your copy.
- "For me works selinux - business in it can?"
=> Sorry, I don't understand this sentence.

Thanks Walt!
Really, I - was mistaken. mgserver should listen to ports 2800-2802, but
it
all the same does not occur.
I have established a debugger gdb, have transferred a folder with
installation mgserver in /opt. Has changed a file mgserver.sh. Has
started
it. And in an environment gdb has executed a command "run." mgserver has
failed to a srtass:
...
(gdb) run
Starting program: /opt/mgserver /interactive
[7]+ Stopped ./mgserver.sh
...
Please, help me in solving this problem.

P.S. For me works selinux - business in it can?

The server uses ports 2800/2801/2802 to communicate with the web-tier.
You'll see these configured in both serverconfig.ini and webconfig.ini
(they should match in both config files). Port 8008 is used by Apache.
As for the server hanging, it's hard to diagnose your problem without
having more info. We have successfully built and tested MGOS on Fedora
Core 4 (kernel 2.6.11-1.1369_FC4) with gcc 4.0.2, and have not
experienced the problem you're seeing.
Are you comfortable running the GDB debugger? You could run mgserver
under GDB, and then find out where exactly it's hanging. Here's what to
do:
1/ change to the mgserver runtime/installation folder
2/ edit mgserver.sh, and change the following line
./mgserver /interactive
to
gdb --args ./mgserver /interactive
3/ run ./mgserver.sh
4/ from GDB type 'run' => mgserver should begin startup
5/ once it gets to where its hung type ctrl-c
6/ enter 'bt' to generate a stack trace

I have made ?? to you have told. Has started mgserver/interactive, any
message at all has not received. Loading of the processor also about 100
%.
Also by your advice has removed catalogues inside
usr/local/mapguideopensource/server/Repositories. Without result. As I
understand, the server msserver after start should listen to 8008 port.
But
it does not occur (netstat does not show it) though ps shows presence of
process mgserver.
Please, help me in solving this problem.

As a start try running the server interactively:
- shut down any existing mgserver process
- cd to the server runtime directory
(/usr/local/mapguideopensource/server/bin)
- enter the command 'mgserver /interactive'
Does the server start up all the way (you should see a "Server started"
message)?
Another thing to try is to start with an empty repository:
- shut down any existing mgserver process
- backup your repository directory
(/usr/local/mapguideopensource/server/Repositories)
- cd into this directory and delete all files/folders except for the
following folders:
Library
DataFiles
Session
DataFiles
Site
TileCache
- cd to the server runtime directory
(/usr/local/mapguideopensource/server/bin)
- enter the command 'mgserver /interactive'
Does that help at all? Does the server settle down to an idle state?

Dear colleagues!
I making and start mapguide-1.0.0 RC1 on a platform linux. But at start
the
server mgserver consumes about 100 % of processor capacity. Thus
mgserver
does not write any a broad gully-files and I not in a condition to
define in
what a problem. I making mapserver both as debug and as release - result
the
same.
