When i google it i find a post somewhere saying about increase the number of threads and the number of the pool, but nothing about this limitation! :( I will test DeadlockDebugger, but the main problem is only happen in the morning (around 8:00am-10:00am. 2007/10/9, Peter Bengtsson <[EMAIL PROTECTED]>: > Are you using any SQL connections or anything like that inside the Zope? > Not SQL, but LDAP yes. 2007/10/9, Dieter Maurer <[EMAIL PROTECTED]>: > > You can try to analyse problems like this with the > "DeadlockDebugger". > > If the "DeadlockDebugger", too, does no longer respond, > you need a C level debugger to attach to your Zope. > > This requires a Python build with debugging symbols (this > is the default when you yourself have built Python) > and some internal knowledge (come back should you need it). > -- > Dieter > Thanks, if deadlockdebugger dont solve i will try gdb! 2007/10/9, Brian Sullivan <[EMAIL PROTECTED]>: > DeadlockDebugger certainly helped me in a similar situation. > > I went through similar blind flailing machinations - modifying threads > and pool sizes (in the end I found not a Zope or Plone coding problem > but some of my Javascript code was inadvertently occasionally causing > a tight looped remote access of a generated page --effectively a self > inflicted DOS attack!) Ok, it wasnt me who code the custom product of the site, i will try what was mentioned here and tomorrow i reply on the list. ty all! ^^ _______________________________________________ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
