Description
At some point after moving away from r5898, a memory leak occoured. I cannot recreate when this happened exactly.
One other updated-point was the r6323.
The current constellation (apache mod_python):
System Information Trac: 0.11b1 Python: 2.4 (#1, Mar 22 2005, 21:42:42) [GCC 3.3.5 20050117 (prerelease) (SUSE Linux)] setuptools: 0.6c7 SQLite: 3.3.4 pysqlite: 2.1.3 Genshi: 0.5dev-r786 Pygments: 0.7.1 Subversion: 1.1.3 (r12730) jQuery: 1.2.1 I've currently updated to the 0.11dev version.
I've looked a little at trac:#6437, trac:#5167, genshi:#166
Note that I had a similar issue (#4885), which was not a leak but a higher memory usage of the new trac version. But this time it looks that there's really a memory-leak.

Python 2.4 is known to have several major memory issues. To get accurate information you will need to use at least 2.5.

wasn't aware of this. I cannot switch to 2.5 at this point, but I'm just activating an Dedicated Server (Suse 10.1, again with python 2.4) to see if I have the same memory problems as with the Virtual Private Server.

I am now on Suse 10.2 with python 2.5 on a dedicated machine, an it seems that the memory problems still exists (will report more those days).

Could you also test with latest Genshi trunk without the C extension? To disable it, install genshi with optional argument: python setup.py install --without-speedups
Are the results comparable?
(BTW: I haven't looked into this at all myself - it is just a tip for testing.)

Replying to osimons:

python setup.py install --without-speedups
I've installed: python setup.py —without-speedups develop
how can I ensure that the C extension is not active (e.g. remained active from older installation etc.).

Is there any piece of code which I can use to produce more precise numbers about memory usage?
I've seen this here within genshi:#166
is the code applicable to any memory problem?

| Resolution: | → worksforme |

| Status: | new → closed |
memory usage is quite high on the dedicated server, but it does not hit the limit.
so, it worksforme now, but only after moving away from the old VPS box. Possibly, just the memory consumptions has increased again.
After restart
(will post another one when it's close before limit)
