<br><font size=2 face="sans-serif">I did not see any difference with the
new _c_urlarg moduIe. I made then several trials and I found that Python
2.4.1 with Twisted 1.3.0 seems to be stable. It now runs for several days
without leak. Something a little bit strange is that I tried Python 2.4.1
with Twisted 2.0.1 and TwistedWeb 0.5.0, but with this configuration the
memory leak is very important. Yet with this config the objects number
(length of gc.get_objects()) is growing with no collection, as I use exactly
the same environment except Twisted version.</font>

There was a leak in the _c_urlarg.c module in 1.3.0, which causes a string<br>
the size of the url to be leaked every request. This doesn't sound
like it<br>
would account for the 96k per 4 requests to me, but perhaps the memory<br>
allocation strategy on QNX explains that.<br>
<br>
Either upgrade to Twisted 2.0 or newer, or grab _c_urlarg.c from that<br>
version or SVN (it's a one-line fix) and recompile it, or just delete the<br>
compiled module -- it'll fall back to the slower pure-python version in
the<br>
standard library, but it won't leak.<br>
<br>
Let us know if that solves it, or at least helps.<br>
