Andy, Brian pointed out today that you aren't just leaking SQL-related objects, you're leaking requests... because requests hold a reference to every traversed object (via PARENTS), if you're leaking reuqests, its a very bad thing. It would also explain why you see so many leaked SQL-related objects if the site is heavily SQL-driven. It may be that your code is keeping references to requests (maybe keeping a global with tracebacks around?), or there is some other circular reference problem. As we haven't had any other corroborative reports of either the DA leaking or the SQLMethods stuff leaking on their own, I'm sort of at a loss to provide a solution. Is there any way to make this bug reproducible on a clean Zope install? Can we boil it down to the simplest case? - C > A new bug entry was added with the following information: > > Title: Memory Leak with ZSQL Methods > > At: http://classic.zope.org:8080/Collector/Collector/2154/sview > > Submitter: andym > > Email: [EMAIL PROTECTED] > > Description: When running a large number of SQL queries using ZSQLMethods I get a memory large leak.

This is obviously sub optimal. _______________________________________________ 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 )
