Hi, There is installation: Zope Version (Zope 2.5.1 (source release, python 2.1, linux2), python 2.1.3, freebsd4) Python Version 2.1.3 (#1, May 5 2002, 06:29:09) [GCC 2.95.3 20010315 (release) [FreeBSD]] System Platform freebsd4 ZODB contains an instance of modified CMFSite (translated in Ukrainian, CMFSiteUA). System works perfectly well even on Zope 2.5.0 on Win32 platform but crashes on FreeBSD. Site was Exported (from Win32) and Imported (to FreeBSD). Local Filesystem View folders were deleted and recreated manually. As soon as somebody tries to touch that CMFSiteUA Zope crashes and restarts. Workaround found is: to enter management interface somwhere deeper, for example /Examples/manage or /Control_Panel/manage. Then Zope loads parts of the system into RAM and appears possibility to run the site. Sooner or later, when there is sufficient time-frame to unload all objects out of the RAM cache (no user activity), system turns back into unusable state and again there is need to bring it up with /Control_Panel/manage... Any hints? BTW, there is absolutely no output in debug mode. Just usual INFO(0) messages on startup. Crash and again usual messages. Watchdow process remains into memory but new child performing requests processinf are respawned. And again INFO(0) messages are flushed into stdout... Any help would be appreciated.
