I'm running a java application on AIX under JDK1.3.<br />
There is a potential deadlock condition that causes the server to stop responding to certain requests.<br />
I can find this deadlock by generating a java thread dump..<br />
<br />
However when I generate the thread dump kill -3 pid,<br />
it generates a javacore file, but the data is truncated in the file..<br />
<br />
In other words it doesnt even give me a listing of all the threads as normal..<br />
<br />
The problem seesm to be that every file I generate is never more than 520k. The files are usually between 518k and 520k and never more...<br />
<br />
I have tried setting the ulimit setttings to unlimited but I think these settings are specifically for the OS core dump and not for teh javacore file..<br />
<br />
Can you think of a reason why the javacore file would be truncated at 520k everytime?<br />

AIX - java thread dump is truncated

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.

Unix OS

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
