[Zope] Managing Catalog indexes is timing out

I can't seem to get into the index manage tab for our main Catalog. It times out before it displays the indexes. Any ideas? (It's got one ZCTextindex and a few FieldIndexes inside) Zope version: (Zope 2.6.2 (source release, python 2.1, linux2), python 2.1.3, linux2) * Python version: 2.1.3 (#1, Apr 9 2002, 22:27:11) [GCC 2.96 20000731 (Red Hat Linux 7.1 2.96-98)]
