Odesílatel: Hanno Schlichting <schlichting@bakb.net> I've a serious problem and don't know where to look further for the error. Hope anyone can help. (Sorry for the crosspost.)

My configuration:

Hardware: 2x 750MHz, 1GB RAM Software: Windows 2000 SP4, Zope 2.6.2, CMF 1.3.2, Plone 1.0.5 and a variety of other products such as CMFForum, CMFCollector, CMFVisualEditor, Epoz, Photo and Photoalbum, TextindexNG, LocalFileSystem.

In detail: In the ZMI I try to change the content of a document. I click change and my browser gets no response. I can watch my zope instance collecting all free memory (~800MB) then suddenly releasing everything and then going into a cycle grabbing up to 40 MB going down to 0 and restarting this, the whole time with a processor load of 100 percent.

Same things does ocassionally (few weeks nothing, then every 2-3 days etc) for me with Zope 2.5.1, W2k TSE. I was moved to Linux Mandrake 9.1, runs without restarting for 1/2 year!

It looks like some kind of infinite loop, but I have no idea what could cause this. I ran debug mode from the console but it tells me nothing. I ran fsrecover and fspack on the database file (about 400MB) but everything is fine.

Our NT admin says me after deep researching that this error is probably in NT and not in Zope but does not know exactly which DLL or so it is. Yes, I was have installed Plone too, but not used. Memory consumes at first look Zope, but in detailed look thins memory consume some component from NT. In finally, my Zope runs now 2-10 times (100 for images) faster than on NT on slower HW and I cannot overload it (I was overload local mirroring machine and not Zope). Try Linux, it is easy to do with Mandrake. Regards JL.
