similar to: Getting number of bytes returned to application by free()?

Howdy, I am attempting to isolate the location of a memory leak in a 4GL program, and have hit a bit of a snag. When I LD_PRELOAD libumem and run the application server, "::findleaks -fdv" reports numerous leaks: CACHE LEAKED BUFCTL CALLER 0000000100b49068 15 0000000100ef2d50 fdcon+0x6c4 0000000100b50028 1 0000000100b72ac0 fdcon+0x6c4 0000000100b49068

Howdy, I was playing around with the malloc/free D script provided by Philip Beevers: http://www.opensolaris.org/jive/thread.jspa?threadID=4224&tstart=15 And decided to change the free:entry probe from: pid24169::free:entry / sz[arg0] / { printf("Freeing %p (size %d)\n", arg0, sz[arg0]); sz[arg0] = 0; } to: pid24169::free:entry / ! sz[arg0] / { printf("[ *

Howdy, I am trying to migrate several scripts to use application defined types, and am running into a few issues. When I attempt to run a script with a application defined type, it looks like the DTrace preprocessor is getting angry with me: $ cat view.d #include "httpd.h" :::acceptconnection { this->addr = (conn_rec *)copyin(arg0,sizeof(conn_rec *)); } $ dtrace -C

Hi, To use DTrace on some C++ code, I found that Apple''s implementation had another option "-xmangled". Its usage could be found here: http://blog.mozilla.com/dmandelin/2008/02/14/dtrace-c-mysteries-solved/ And it could be found in Apple''s man page: http://developer.apple.com/documentation/Darwin/Reference/ManPages/man1/dtrace.1.html Is it possible to have that

Howdy, I wrote a pair of scripts to measure file and NFSv3 operations, and thought I would share them with the folks on the list. You can view the script output by pointing your browser at the following URLs: Per Process NFSv3 Client statistics (inspired by fsstat/nfsstat): http://daemons.net/~matty/code/nfsclientstats.pl.txt Per Process File Operations (inspired by fsstat):

Howdy, I installed Nevada build 49 in a parallels VM on my intel mac mini, and when I run the following DTrace script: $ cat follow.d #pragma option D flowindent; pid$target:::entry, pid$target:::return {} $ cat format.cmds disk 0 exit $ dtrace -s follow.d -o follow.out -c "/usr/sbin/format -f format.cmds" dtrace: script ''follow.d'' matched 13641 probes The system

I would like to profile heap usage on a per thread basis in a large application process. To do this I am tracking calls to malloc and free with the attached script. Everything seems to look OK with some simple test programmes, however, when I track the live system, the results suggest that one thread has grown by approximately 1Gb and I would be surprised if this was true because I ran pmap -x on

Hi, This is regarding Dtrace usability for memory leak detection. We have real-time application written C++ which runs on Solaris 10 having a problem that''s the my application grows in size from 130 Mb to 450Mb in around 15 days. So there is two possibilities with the application growth of memory due to Size growth of Dictionary Objects (Like Maps) and Memory Leak.

Hi, I have mentioned before that we have added some sdt dtrace probes in SAX, our APL interpreter. Encouraged by Angelo and Jignesh, I have created a small document (5 pages) describing our experience with it, together with some problems we have encountered and some scripts we use for pretty-printing dtrace outputs. The said document can be found at

Howdy, Is there a method to get the number of elements in an aggregation? Are the results stored in an aggregation guaranteed to be in any type of order? Thanks for any insight, - Ryan -- UNIX Administrator http://daemons.net/~matty

I have inserted some probes in my application, and it works great in the "debug build" I have been using. So I wanted to look at the "overhead" introduced by inactive dtrace probes in my application. I am using the Sun Studio 11 compiler, so I added the following options: -xO5 -g0 -xbuiltin But this breaks the linking of my application. Undefined first

Hi , I have c++ server application in solaries 10 . Day by day memory usage is growing i try to find memory leaks with MDB and DTRACE and no leaks found. how can we find reason for growing memory , can we know which memory sigment is cause for growing memory usage Thanks in Advance.

------------------forwarded------------------------------------ This is to help my customer to migrate their IBM websphere 6.0.2 to run on solaris 10 platform. Customer is eager to use the dtrace agent of JDK (https://solaris10-dtrace-vm-agents.dev.java.net/ ) to benefit their IBM websphere server, I am not sure whether we can use this agent in IBM websphere bundled JDK whose version is JDK

Howdy, We are running zones on a number of Solaris 10 update 3 hosts, and we are bumping into an issue where the kernel doesn''t clean up connections after an application exits. When this issue occurs, the netstat utility doesn''t show anything listening on the port the application uses (8080 in the example below), but connections are still listed in the ESTABLISHED state: $

Hi, Can I use DTrace to determine memory status? 1.Total Physical Memory, Used Memory. 2.Total Swap Space and Used Swap Space. I did find few DTrace scripts but had too much in them and I am unable to chop off unwanted lines of code due to lack of knowledge. It will be very helpful if some one can share the piece of code that serves my purpose as mentioned above. Regards, Ramesh. Ramesh

A small script to see what SCSI commands are being issued by a system: http://blogs.sun.com/roller/page/chrisg?entry=scsi_d_script Still work in progress as I needs to handle larger CDBs but it is a start, since I don''t have a disk that big it is not a problem for me yet. Also getting the return scsi packet is a hack but so far I can see no alternative short of knowing about all the

Hi All, I''ve got a problem when I have USDT probes in a static library and in the application code outside of the library. I build the static library containing some USDT probes, glomming everything together (ld -r) before creating the .a file to preserve the probe symbols. This all works fine. I build an application which also has some USDT probes. When I build the application which
