From: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=179874 Description of problem: Of course you shouldn't do this, but if you try to add an observer to frysk, it hangs. I get this on the terminal: click : frysk.gui.monitor.ProcData@4e0f110 Exception in thread "Thread-2" ptrace.attach: Operation not permitted (process 6707) at java.lang.Exception.Exception() (/usr/lib/libgcj.so.6.0.0) at java.lang.RuntimeException.RuntimeException() (/usr/lib/libgcj.so.6.0.0) at java.lang.Thread.run() (/usr/lib/libgcj.so.6.0.0) Version-Release number of selected component (if applicable): frysk-0.0.1.2005.12.14.15.12-0.EL4.3 How reproducible: 100% Steps to Reproduce: 1. Install frsyk 2. as a user, sudo frysk 3. add any observer for the frysk process Actual results: frysk hangs Expected results: the observer is not added, but the app continues to run (maybe displays a warning?) Additional info:
This may have been fixed in the RHEL4-U3 update (and therefore in head). There was an error in the way we were associating parents in the treeview. Can you retest and report?
In addition, the user is now not allowed to attach to the *same* frysk process that the user is interacting with, but only other ancillary and incidental frysk processes running on the system. Closing, as OP did not reply, and this bug has been not been seen, and potentially cannot happen with the code changes past OP report.
