Hey, Im able to reproduce a crash from plockstat everytime Im tracing a JVM pid. I do recall a problem related with this one, but not clear if this has been fixed in U3 or is it planned for U4 ?

So I realize this is somewhat stupid, and I''ve actually gotten myself out of kmdb to kill my dtrace script but this has happened in the past and I''m wondering if there''s any better way around it than hitting :c a bunch of times. Say you set a breakpoint() to fire in a common function. This will drop you into kmdb where you can do some debugging, you take a look around

Hello, The Hotspot JVM Runtime group would like to put forth a project proposal to improve the capabilities of DTrace''s ustack()/jstack() actions to better handle non-standard user stack frames. This email will describe the background, the problem, and our proposed solution. We''re interested in getting a sponsor for this work to help us with the process of getting the

Hi, I''m posting a question hoping someone will know the answer off hand thereby reducing my search time. :-) With USDT probes, the tracepoint is only installed by libdtrace itself, never by the drti ioctl. So whenever I run a program with an USDT probe, no tracepoint is installed. Only after I run the dtrace command the tracepoint is actually installed on the victim process. My question

Hi, If you have a custom kernel (and therefore have duplicates of everything in /kernel in your custom kernel) and have noticed that when you try to use anonymous tracing, dtrace adds multiple copies of the forceload directives to /etc/system, e.g.: * vvvv Added by DTrace * * The following forceload directives were added by dtrace(1M) to allow for * tracing during boot. If these

Hi all, What is the correct way to give one non-root user the ability to use DTrace with providers running in a process by another user? Through the Web Stack project and some work by Ludovic Champenois and Nasser Nouri, we have done a bit of work to bring together parts of chime, the Web Stack Apache, Ruby and PHP providers, and stuff reused from the DTrace toolkit. It''s in

How would I determine the address of the ulwp_t structure for the current thread of a process from a 32-bit i386 executable looking at a 32-bit executable? (This is in support of a fix for 6593259: "libdtrace should prefer pid probes to breakpoints".) For example, if I compile the following code 64-bit snippet, I can get that address from 32-bit or 64-bit executables:
