Fwd: Memory leak in python

[Abhishek S]

Hi Nick,

Thanks for reply... Please include me in reply.
Currently i am not in the list (i will subscribe soon)

I upgarded to 2.4.1 - still the same issue.

Nick>
Thats not a lot of leak - have you done that over a
longer time period?

Abhi>
I have tried for 4 days. It has reached 150MB.

Nick>
Are there any objects in gc.garbage?
>>> gc.set_debug(gc.DEBUG_LEAK)
>>> gc.get_debug( )
62
>>> gc.collect()
0
>>> gc.garbage
[]
>>>

Abhi>
There is none.

Nick>
Are you writing objects with __del__ methods?  If so
then that is your problem probably.

Abhi> 
I have not written any __del__ methods.

Nick>
Have you written any C extension modules in C?

Yes. Many - All of them are called only 
when the app starts. And never called again.
Till then it is stable only - 16MB used.

I have tried following - let me know if you need any
more details.. and want me to try something.

1)
I found a "sizer" python program. Which gives me the
module which is growing. It indicates that __main__ is
growing.

__main__': 4000774

2) I tried following.. (not smart but..)

def f():
 c = gc.get_objects()
 j = 0
 for i in c:
   j = j + 1
   try:
     tmp = len(i)
     if tmp > 1000:
      print "(c[%d]) (%d)," % (j-1, tmp)
   except:
     pass

it prints me as folows:

l(c[175]) (7336),
l(c[12475]) (1260),
l(c[12477]) (1260),
l(c[12479]) (1381),
l(c[12481]) (1381),
l(c[34159]) (1200),
l(c[37144]) (28234),
l(c[37191]) (28286),
>>> type(c[37191])
<type 'dict'>
>>> for k,v in c[37164].items():
...    print k, v
...    b = b + 1
...    if b > 30:
...       break
...

This two dict in the last is growing slowly..
I am not maintaing any dict with such indices and
value.

Any clue? 
Please let me know what else to check and how!

At the time i am ending this.. module size..
'__main__': 7926830,

Thanks,
Abhishek
