Hi all, I have isolated the memory leak problem on a naked 2.3.3 Zope. I have on ZPsycopgDA and two SQL Methods, one SQL Method contains DTML-IFs and DTML-ELSEs and REQUEST.sets the other SQL Method contains the rendered query of the first, this means there is pure sql in it. Both methods cache there results 60 secs. Zope runs with 4 threads. I wrote a test-script wich opens 4 threads and each thread call the second SQL Methods "manage_test" via wget. After a restart my zope-processes are around 12MB. Then i start my script and before i receive any result all processes are grown up to 26MB. Even if after i start my script nothing happens, but before i receive the result the processes grow up, maybe i think this is the time where zope gets the results from the database and "puts" it into the Results-Class( i am right at this point ?). But is the problem in the ZSQLMethod( where the results were cached ) or the ZPsycopgDA ??
