Hi, in the past days I have been experiencing mysterious crashes, under heavy load conditions with Zope version: Zope 2.1.6 (binary release, python 1.5.2, solaris-2.6-sparc) Python version: 1.5.2 (#8, Nov 16 1999, 10:05:41) [GCC 2.8.1] System Platform: sunos5 Since that was the sensible choice, I was running Zope as user "nobody". Completely by chance, I run it as a 'normal' user (neither root, nor nobody). I was surprised to realize that it would not crash any more, no matter how much I pounded it with wget and similar tools. I was running it from a terminal, where every now and then interesting messages pop up: ------ 2000-06-30T22:33:44 PROBLEM(100) ZServer warning: server accept() threw EWOULDBLOCK ------ 2000-07-01T07:58:31 PROBLEM(100) ZServer Server accept() threw an exception ------ 2000-07-03T03:59:43 ERROR(200) ZServer uncaptured python exception, closing channel <zhtt p_channel connected 132.248.10.194:1073 at 70e4d8 channel#: 15840 requests:13> (socket.er ror:(9, 'Bad file number') [/usr/local/zope/ZServer/medusa/asynchat.py|initiate_send|211] [/usr/local/zope/ZServer/medusa/http_server.py|send|400] [/usr/local/zope/ZServer/medusa /asyncore.py|send|237]) ------ 2000-07-03T14:50:34 ERROR(200) ZServer Bad HTTP request: GET /Zorba/logo-solo.gif >logo-s olo.gif ------ 2000-07-03T18:43:50 ERROR(200) ZServer uncaptured python exception, closing channel <zhtt p_channel connected 200.15.155.65:3719 at 66da40 channel#: 22958 requests:1> (socket.erro r:(9, 'Bad file number') [/usr/local/zope/ZServer/medusa/asynchat.py|initiate_send|211] [ /usr/local/zope/ZServer/medusa/http_server.py|send|400] [/usr/local/zope/ZServer/medusa/a syncore.py|send|237]) Could be that, when running as nobody, Zope could not do something that it has do after an exception ? It could be something as simple as writing to /tmp or logging things with syslogd ... anyway, it could be something that Solaris prevents it from doing, which in turn causes the crashes. Now, I am still keeping my fingers crossed for tomorrow I have a demo. So, apologies if all this is old hat, and thanks for the wonderful list environment.
