[Twisted-Python] why my my twisted program hanged and crash

[weiwei]

hi,all!

Some day ago,I found my twisted program hanged and I try to kill it with "kill -15 mypid",then after some minutes,the program crashed and generated a core file.

So I analyze the core with dbx(my os is AIX 5.3),the following is the result:

Type 'help' for help.
[using memory image in core]
reading symbolic information ...

Segmentation fault in extend_brk at 0xd02f97c0 ($t1)
0xd02f97c0 (extend_brk+0xc8) 90040004        stw   r0,0x4(r4)
(dbx) where
extend_brk(internal error: assertion failed at line 3626 in file frame.c
??, internal error: assertion failed at line 3626 in file frame.c
??, internal error: assertion failed at line 3626 in file frame.c
??) at 0xd02f97c0
(dbx) 

I don't know why this happened:
1) why my twisted program hanged? (I use pollreactor)
2) why my twisted program crashed and generated a core file?
