We have various WiTango app's (W2K, MS-SQL 2000, WiTango 5.0.1.054) that talk to a few 
different databases, but are all running on the same IIS machine (there's only one 
WiTango service running on this machine).

Some times a query or process on database A will block other queries for a long time 
and we see the count of current connections to IIS start to climb as more and more 
.taf's are waiting for the database to respond.

However, what confuses me, is that other .taf applications that make queries to the 
same SQL server, but to database B are also stuck waiting.  Even though these queries 
have nothing to do with the blocked tables.  Eventually, the count of current 
connections to IIS reaches about 260 and levels off.  At this point, no WiTango 
applications respond at all.  When the blocking query finishes (or is killed) the 
requests start completing and everything gets back to normal.

I'm confused as to why table blocking on database A would affect WiTango applications 
that are talking to database B.  It seems that WiTango is holding unrelated requests 
in queue until the one's that are blocked complete.  Is this what's happening?  If so, 
is there anything we can do about it?
