[HPADM] program creates tr.<PID>.<NUM> files ?

Hello,


I just compiled and tested a program of mine on some HPUX machines.

$ uname -a
HP-UX rp3440 B.11.31 U 9000/800 325855341 unlimited-user license

The binary uses threads :
$ ldd mybin
libelf.2 => /usr/lib/pa20_64/libelf.2
libm.2 => /usr/lib/pa20_64/libm.2
libpthread.1 => /usr/lib/pa20_64/libpthread.1
libc.2 => /usr/lib/pa20_64/libc.2
libdl.1 => /usr/lib/pa20_64/libdl.1


When running, it creates tr.<PID>.<NUMBER> files :
$ ls tr*
tr.02735.00001 tr.02740.00005 tr.02740.00013 tr.07180.00006 tr.07180.00014
tr.02735.00002 tr.02740.00006 tr.05651.00001 tr.07180.00007 tr.07180.00015
tr.02735.00003 tr.02740.00007 tr.05651.00002 tr.07180.00008 tr.07180.00016
tr.02735.00004 tr.02740.00008 tr.07180.00001 tr.07180.00009 tr.07180.00017
tr.02740.00001 tr.02740.00009 tr.07180.00002 tr.07180.00010 tr.29737.00001
tr.02740.00002 tr.02740.00010 tr.07180.00003 tr.07180.00011 tr.29737.00002
tr.02740.00003 tr.02740.00011 tr.07180.00004 tr.07180.00012 tr.29738.00001
tr.02740.00004 tr.02740.00012 tr.07180.00005 tr.07180.00013 tr.29738.00002


Those are growing up constantly, here more than 860MB:

$ ls -l tr.07180.00011
-rw-r--r-- 1 root sys 863256576 Sep 12 06:30 tr.07180.00011

Here's an example of their content :
$ head tr.07180.00011

I'm convincend the code of the sources compiled in this binary do not
explicitely generate this kind of file. I'll try working on a small
source to reproduce that ant try to understand what's going on, but
if any of you had an idea, any hints welcome !

FWIW, I'm experiencing the same on another Itanium HPUX 11.31, but
it's just fine on 11.23.


TIA,

Flavien.
