profiling doesn't stop [message #508978]

This is my first time to use TPTP to profile my java program, and I got into some problem.

Usually my java program can terminate in about 30 seconds. But by profiling it, it seems to take much much longer time. I tried to profile it for three times, and for all of them it didn't stop after 1 hours. For one run I had to manually stop it. For the other two runs, when I came back to my computer after a few hours, Eclipse just disappeared, without any error message left.
Another thing that I found is, even when I pause the profiling, Eclipse still uses nearly 100% CPU time.

I wonder whether there's something wrong and how I can fix it. Thank you in advance.

I tried again. After running for 5 hours, Eclipse once again disappeared without any warning or error message. About 500MB memory was released. A file named "servicelog" of size 2G is found in the Eclipse workspace under " .metadata\.plugins\org.eclipse.tptp.platform.iac.administrat or\config ". However, ACServer.exe continues to use nearly 100% CPU time. Any idea of what happened?

Ok, with numerous timeout I finally managed to post my reply but it seems to be posted for three time... Sorry about that but I can't find out a way to delete them...

Hi,

What TPTP release are you using? Was there any filtering configuration in
your Java profile session? Try the following, shut down Eclipse, kill the
ACServer.exe and any dangling java.exe running on your machine (check Task
Manager), delete or move the existing servicelog file out from the default
directory; then restart Eclipse workbench with a fresh workspace, and start
a fresh profile, configure the filter similar to the following:
myPackageName* * INCLUDE
* * EXCLUDE
where myPackageName is the package prefix of your target Java application.
See if that helps.
Could you also send me the servicelog file if the problem happens again, the
new one created in the default directory.

Thanks for the suggestion. I'm using tptp 4.4.0. The filter is the default one that includes all my packages and excludes the others.

I just looked at the option of the "execution time analysis" under the profile configuration -> monitor tab. The default one is "show execution flow graphical details". Now I changed it to "show execution statistics", and the running time is reduced to 20min, which is still slow (without profiling it's 10 sec) but much more acceptable.

Hi,

Please try also tune your filter configuration to filter in only the
package/class of your target, and exclude everythign else to fasten the
profiling process.

This time I'm trying to use the memory analysis but get a similar problem. Again it's my java program that usually terminates in about 20 sec, but with the memory profiling it has been 20 hours now and it is still running. I clicked the terminate button a hour ago, but no good so far. I set the filter to only include the packages that I'm interested in and exclude all the others. I also looked at the options of memory analysis but there's only one check box which is unchecked by default.

I just terminated the Eclipse process, but now the ACServer process is using 100% CPU, and it's writing to the servicelog which has grown from less than 1mb to 323mb now.

Hi
Could you try terminat the ACServer process and make sure there is dangling
Java process on the same machine. Then start Eclipse with a fresh workspace
and rerun the scenario again. Note thaere is no need to start any AC
manually as Integrated Agent Controller will handle the launch and
communicate with the Profiling Agent.
