[Zope] Zope exits with error code 10 or 11

Anyone know what error codes 10 and 11 are? Our recently installed Zope 2.5.0 seems to be restarting itself about once a day. This is Zope-2.5.0-src (built using wo_pcgi.py) on Solaris 7 with Python 2.1.2 compiled with gcc 2.95.2. 2002-04-24T17:29:45 ERROR(200) zdaemon zdaemon: Wed Apr 24 13:29:45 2002: Aiieee! 10866 exited with error code: 10 2002-04-25T18:10:32 ERROR(200) zdaemon zdaemon: Thu Apr 25 14:10:32 2002: Aiieee! 20802 exited with error code: 11 2002-04-26T20:13:42 ERROR(200) zdaemon zdaemon: Fri Apr 26 16:13:42 2002: Aiieee! 26081 exited with error code: 10 2002-04-27T04:02:58 ERROR(200) zdaemon zdaemon: Sat Apr 27 00:02:58 2002: Aiieee! 1972 exited with error code: 11 Thanks, Doug
