Thread v4.25b4 server, 11280 & 11294 errors.

Since upgrading 1 server from 4.24b1 to 4.25b4 I have been sporadically getting 11280
errors, not able to connect.

A few days ago was unable to connect on 12005, (even with dbsys) but could connect on
12006. Server is not dedicated, and had been started a few hours earlier and no other
programs had been used, meaning no web browsing, etc. by any user.

Today got 11280, then later 11294, database does not exist. Tried to access the database
using Administrator, but it was not listed.
Uninstalled server and reverted back to 4.24b1. Database was then available.

Here is part of the log:
5/17/2007 8:27:49 PM [ERROR] Engine error [DBISAM Engine Error # 11294 The database
'WinClean_DBISAM_v4' does not exist on the database server at ''] [Client Version: 4.23
User Name: admin Address: 127.0.0.1 Encrypted: No Request:

Note it reports client version 4.23.  Is this a problem, having a 4.23 client with 4.25?
Would there be a problem with a 4.25b4 client with a 4.24b1 server? (I think the dbsys
version was 4.25, but would need to recheck.) I'm not clear at what point the version
differences with components compiled in a client program becomes a problem.

The problems started after 4.25b4 install. Previous version was 4.24b1. [Windows xp sp2.
Dell P4 with hyperthreading.]

Also, these errors are happening on one machine, that is client and server are on the
machine I mentioned.

Are the "database not found" errors sporadic ?  If so, then the issue most
likely does not have anything to do with the DBISAM version.

What was the request ?  It got cut off above.

It shouldn't be an issue, no.  DBISAM automatically does version checks in
all calls to ensure that it behaves as expected for the version of the
client being used.

Sorry about the bad cut & paste. Here is the full line from the log file:

5/17/2007 8:27:49 PM [ERROR] Engine error [DBISAM Engine Error # 11294
The database 'WinClean_DBISAM_v4' does not exist on the database server
at ''] [Client Version: 4.23 User Name: admin Address: 127.0.0.1
Encrypted: No Request: REQUEST_OPENDATADIR Thread: 2480 Session: 43909128]

The "does not exist" happened one time that I know of. The 11280's are
fairly common, to the point where things look unstable to the end user.

When I was able to check, at the time of the 11280 in my program, even
dbsys could not connect on 12005. The first check I did a few days ago,
the administrator utility could connect on 12006. On this last
occurrence yesterday, even the administrator utility couldn't connect as
the database wasn't listed. I thought possibly the configuration file
was ruined, but after reverting back to 4.24, the config file was usable.

Okay, then it probably was a one-off issue unrelated to the 11280's.

Are you using a software/hardware firewall at all ?  It sounds like
something is messing around with the connectivity and causing sporadic
issues.

When the initial error occurred, yes, some IP supplied free Computer
Associates antivirus, containing an old version of Zone Alarm. It was
then turned off. Things still didn't work until reverting the server to
an older version. Of course a restart would have also temporarily fixed
things up.

No further errors since reverting.

By the way uninstalling the zone alarm will be "interesting."  Expect
blue screens and maybe an unbootable pc. I no longer recommend software
firewalls. Haven't used one in years. Don't even use real time
antivirus, just email scanning and pre-install scanning. It's all FUD.

I think this is a red herring.  There is no difference between 4.24 and 4.25
in terms of the server calls other than two changes:

- One for including lost data events for adding primary and secondary
indexes
- One for fixing an issue with SQL statement preparation

Neither of these has anything to do with connectivity issues.

I agree, they're a mess and more trouble than they're worth.  A hardware
firewall works better in terms of not messing with the OS, and comes with
most routers now.
