I changed to using jdk 1.5 since I read that support for 1.4 seems to be removed ( that might be the reson for my problems in previous post).

I am still doing the profiling locally.

GUI: Fetching children of data collector ... 0%

It hangs there forever and log is filled with ( see below).

Hi,

I could not reproduce the problem you reported here.
Did you change the jdk version of the Eclipse workbench or the Agent
Controller setting under Preferences.
Could you open a defect on TPTP bugzilla system and list the step and setup
you have to help the developer reproduce the problem and investigate?

I installed TPTP 4.6.2 today. It worked initially without problems, and then started hanging at the Monitor window. The exceptions I saw in the logs were same as described above.

The problem turned out to be simple. Integrated Agent Controller runs on port 10002 by default. Somehow, though I shut down Eclipse, Agent Controller didn't die, it was still running, listening on 10002. Try this to see if it's running

telnet localhost 10002

Once I killed that process, I started up Eclipse, and TPTP worked again.

TPTP is great. Suggestions to TPTP guys:

1. There appear to be cases where Eclipse can exit, but the Controller lingers on. Should be fixed.

2. If there was anything like "TPTP controller is unable to establish connection on port 10002" in the logs, I would've figured this out in 5 minutes instead of half a day.
