Hi all, I need some help here - over the past few days two different Zope servers have gone into the 'hanging' state, where they don't reply to further requests. When the first event happened I didn't take a 'top', today, I've managed to get one. The process causing the problem is 12482. From previous messages, I believe that the python CPU can go up to 100%, obviously this isn't happening here. This happened when I asked the Zope server to make a MySQL query. The MySQL server is running fine and I can get to it from a command line interface.

Both servers are Zope 2.1.2 source distributions running under Solaris 5.6

Note that 2.1.2 has a known hanging problem under high load. This bug is fixed in 2.1.3 -Michel
