Re: [Zope-dev] memory eating Zope..
Hi Christian, It looks like you're leaking requests. This is often the consequence of setting an attribute on the REQUEST object which is aquisition wrapped. For instance: REQUEST.adtmldoc = REQUEST['PARENTS'][0] When requests leak, references to all the objects referenced within the request (acquisition wrappers, etc.) leak as well. This can be disastrous and gets worse when the site is busy (when there are more requests). It used to be the case that tracking this problem down was tediously difficult, and involved basically a binary search for leaks in all methods on the site. But now, finding the cause is likely a job for Shane's LeakFinder product: http://www.zope.org/Members/hathawsh/LeakFinder . Note that this is likely caused by some sort of brainbending circular reference problem that might be helped by Python 2.X's cyclic garbage collector. - C Christian Scholz wrote: > > Hi there! > > I got another problem with my Zope server and that seems to be > a memory hole.. > > I am using Zope 2.3.2 with Python 1.5.2 now on SuSE 7.0 (this > seems to solve the hanging problem, which appeared on 7.1) and > I use Python Script, ZSQL methods, ZMySQLDA and ZPatterns. > > Now using top I see over time how the memory consumption of the > zope processes grows, which means I have to restart once a day > as it then becomes too slow.. > > When looking at the refcount in the debug section I see the following: > > Acquisition.ImplicitAcquirerWrapper: 7509 > DocumentTemplate.DT_Util.Eval: 719 > Products.ZPatterns.Expressions.Expression: 716 > ZPublisher.HTTPRequest.HTTPRequest: 457 > ZServer.HTTPResponse.ZServerHTTPResponse: 450 > ZPublisher.BaseRequest.RequestContainer: 447 > > So Acquisition.ImplicitAcquirerWrapper seems to be referenced > quite often (this is in an early state..) > > So does anybody know what this might cause?

[Zope-dev] memory eating Zope..
Hi there! I got another problem with my Zope server and that seems to be a memory hole.. I am using Zope 2.3.2 with Python 1.5.2 now on SuSE 7.0 (this seems to solve the hanging problem, which appeared on 7.1) and I use Python Script, ZSQL methods, ZMySQLDA and ZPatterns. Now using top I see over time how the memory consumption of the zope processes grows, which means I have to restart once a day as it then becomes too slow.. When looking at the refcount in the debug section I see the following: Acquisition.ImplicitAcquirerWrapper: 7509 DocumentTemplate.DT_Util.Eval: 719 Products.ZPatterns.Expressions.Expression: 716 ZPublisher.HTTPRequest.HTTPRequest: 457 ZServer.HTTPResponse.ZServerHTTPResponse: 450 ZPublisher.BaseRequest.RequestContainer: 447 So Acquisition.ImplicitAcquirerWrapper seems to be referenced quite often (this is in an early state..) So does anybody know what this might cause? Or maybe how to track that problem down? (seems to be a long way with that server to become it stable.. ;-) Thanks in advance!

If the software is compiled from source, I expect it to tell me what system/software it was *actually* compiled with, and in the case of python *actually* running on, not some string hardcoded into a text file. If the string is not dynamically generated, I'd rather it not lie; ie: it should just give the Zope version. --RDM ___ Zope-Dev maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope )
[Zope-dev] WEBDav - ZClass Problems
I have two ZClasses, one with base class of CatalogAwareBase and ZDTMLDocument, the other with base class of _ZClass_for_Renderable and CatalogAwareBase. Manager role has the full set of permissions for the classes. ZInstances are created as expected, TTW. However, when I try to manage these ZInstances via a WEBDav client, the WEBDav Server simply doesn't show that the objects are there. Is the WebDav server setup to ONLY manage DTMLDocuments and DTMLMethods? I have had no problems with my WEBDav client when managing these traditional Zope objects. Is this a side effect of ZClasses or of CatalogAware? As a side, the FTP client has no problems with these ZInstances. What gives???
