"Fetching children of data collector" task hangs [message #135394] Wed, 03 September 2008 04:42 Go to next message
Eclipse User
Originally posted by: torbjorn.ghostwriter.no

When opening the "Profile Configurations" dialog, a task called "Fetching
children of data collector" task starts and never stops. It says its
"filtering data collectors" at 0%. The contents of the "Monitor" tab is
constantly "Pending..."

I've uninstalled the TPTP plugins and started eclipse with -clean, but
nothing seems to help. Is there something I can do to fix this, or should I
file a bug?

I've installed the following TPTP plugins (using P2):
Log and Trace Analyzer
Monitoring Tools Project
Platform Project
Reporting with BIRT

Which version of Eclipse and TPTP are you using? On what operating system?

Hi,

I have exactly the same problem: I just downloaded a fresh version of
"Eclipse for java developer" + software update to get all the TPTP plugins
into "test and profile".

I'm on linux mandriva 2006.

Another clue: while it's "fetching...", after a few minutes, I have the
following error in the terminal from which I launched eclipse:

Exception in thread
"org.eclipse.hyades.execution.core.task.ReusableThread@837986"
java.lang.NullPointerException
at
org.eclipse.hyades.execution.local.util.AgentControllerDescr iptor.versionIsAtLeast(AgentControllerDescriptor.java:67)

at
org.eclipse.hyades.execution.core.task.ReusableThread.run(Re usableThread.java:131)
at java.lang.Thread.run(Thread.java:619)

Thanks a lot for your help,

Regards,
Christophe

OK, it's pretty weird: I didn't touched to my eclipse since yesterday
(just maybe close and reopen it), but now TPTP is working fine !
It's not pending anymore, monitors are listed within a few seconds.

I'm sorry, but I have no explanation: no install, nothing... ?!

Maybe a conflict with another (sleeping, zombi,...) process ?...

Eclipse 3.4 and TPTP 4.5 require Java 1.5 or later. Make sure to launch
Eclipse with an 1.5 (or later) JVM.

HTH,

I have the same problem. I'm on Ubuntu 8.10 with a fresh install of
Eclipse 3.4.1. I used the software update to install TPTP.

Hi,

Please try the following: (Assuming you are doing local profile)
- Close Eclipse workbench
- Check in Task Manager to ensure there is no dangling eclipse.exe, java.exe
and ACServer.exe running no the machine.
- Restart Eclipse workbench with a fresh workbench
- Go to Windows > Preferences > Agent Controller > Host, select "localhost"
and Test Connection, make sure the AC is connected with no problem.
- Open a Profile Launch Configuration and try fetch the agent again.

Hi Samira,

Glad to know it is working now.
The problem could be a dangling AC (Intergrated Agent Controller) process
which maybe the result of an abnormal shutdown of either a Profiling Agent
or the Eclipse workbench.

I'm experiencing this problem as well, and the solution above didn't work. I'm running TPTP all-in-one 4.7.1a on Ubuntu 8.10 (Intrepid). Like everyone else has said, the "Fetching children of data collector" task starts and never stops and a bunch of NullPointerExceptions get printed out to console.

any help would be appreciated.

thanks

Fetching children of data collector (16%)

Server on Linux
Eclipse on Windows XP
Java 1.6
TPTP Profile on Server Version: 4.5.1

Any help is much appreciated.

Just uncheck the check box "Contact all update sites during install to find required software" in the "install new software" dialog.
