Hello Blair,

One of the errors follows:
bin/orca: warning: cannot create Orca::HTMLFile
object: cannot open
`/home/tlabai/rlj/oooo/orca/data_store/html_out/o_bbuxas04-weekly.html.htm'
for writing: Too many open files.

BUT let's forget the problem for the time being!

I currently have 0.27b1 running and have started
working on moving to 0.27b2. All the percol files are
compressed with bunzip2.

I thought about putting the 0.26 patch on 0.27b1 but
am holding off pending the result of getting 0.27b2
running.

For all its worth, as it turned out all the html pages
that were lost came back after a while. I assume after
a series of data updates. All looks fine now.

Thanks for your help.
