We are using DBISAM version 4.19 in our production server being accessed by IntraWeb
Application server. We have two physical machines, one for the DBISAM database server and
one for IntraWeb Server.  We have been smooth sailing until last night when our web
customers (FireFox or iExplorer) reported Error Compressing data (#15001). This is related
to failure in compressing the buffer and should never happen with DBISAM. Both systems are
running on Windows XP Pro and we have up to 100 users concurrently connected during peak
load to the IntraWeb server, and just about 35 or less to the DBISAM server during peak load.

Now that this error #150001 happened, what could have caused this? Are there hackers
trying to go around our system, some yet unknown exploits and we are ground zero attack?
Or something else trivial. Any insights would be appreciated.

I remember getting this error a while back when I was testing various
session settings. I think it was when I had RemoteTrace on for a session. I
never researched the exact cause or reported it to Elevate because I was
doing so many tests it was hard to reproduce.

There's a bug fix that microsoft broke IE with that sounds like this. It
is to do with HTTP 1.1 compression. I'd say that was your problem...

By bug fix, I mean security update. If I see where I saw the info again,
I'll let you know.

Did the error only show up with the web users ?  Is the DBISAM database
server exposed to the Internet at all ?

Okay, found the message I saw:
-------------------
However, having now looked, there /is/ a MS patch out for the problem, but
it's one of the ones you have to specifically ask MS for:
http://support.microsoft.com/kb/923762/en-us

Here's a posting from the newsgroup which was obviously put up before the
patch was released:

"Microsoft is working on a fix for this.  If your computer is windows
XP or windows 2000 the workaround (which totally solved the problem for me
is:
1. start Internet exployer 6.
2. on the TOOLS menu, click INTERNET OPTIONS, and then click the ADVANCED
tab.
3. In the SETTINGS box, click to clear the USE HTTP 1.1 SETTINGS and then
click OK and apply
reboot.   
It should now work fine.

the symptom this worksaroud is: IE unexpectedly exits when you view a Web
site that uses the HTTP 1.1 protocol and compression.  This occurs on many
computers after the recent 918899 update being installed.
hope this helps!"

Matthew,

Thanks for this. I've noticed IE crashing now and then on certain pages of
well-known web sites (eg, NY Times) since the last MS update. Have made this
change and we'll see if this stops happening.
