[Koha] Two odd, possibly connected behaviors from Koha...syssasdasd

[Andrew]

Hi All,

Here's the deal:

We are currently running Koha 3.0 on Debian 4.0.1 served to various buildings
via Fiber Channel on our LAN. The first problem is a lag in search and query
functions performed by several of our librarians located in a building across
the street. The problem seems to be localised to them, and I see no identifiable
issues with the network itself, of their exterior Internet connection - browsing
outside of Koha is snappy and "normal". I want to assume that this problem is
purely a physical connection issue with the fiber channel of the switches, but I
wanted to explore other possibilities that it might be something else specific
to Koha. I'm new to administering Koha, though I've used it for queries and
searched for two years. 

The second problem is a possible result of a Global Update that was performed
just before I started at this position. After the update several catalogue
entries literally "went missing" when searches were performed, only to turn up
gradually over the course of three days. there are also several duplicated
entries, fully functional and searchable via MARC,etc.. 

All of the errors to records seem to have occurred to the records that were
being entered into Koha during the actual time period of the Global Update, and
don't appear to be propagating across the database. Could this simply be fixed
by updating the MARC records and initiate index updates? I can try things out in
a sandbox environment if I need to, but I'm being very careful so not to amplify
a small problem into something that might take our OPAC down for a full day or
two. In my opinion our copy of Koha is stable and usable, but I'd like to come
up with a solution as fast as I can to eliminate the duplicates.

Ideas?

Thanks
