Re: Channels taking coffee breaks?

Here's the list of changes in version 2.5:

AddScriptTimeout can extend timeout from time of call using bFromNow argument.
Fixed problem that in rare cases caused channels to be restarted even after AddScriptTimeout and SetScriptTimeout methods were invoked.
Resolved FoxWebCtrl Socket Error 10054 and 10053 issue.
Broker does not write 10054 error when the connection with the channel is broken (usually as a result of a channel restart).
Channel re-registers with the broker every 30 seconds, to verify that the broker knows it is available.
Added code to reject URLs that contain \..\ sequences (this did not work with most web servers anyway).
Error handler handles large memvar dumps (thousands of memvars) gracefully.
Error handler uses a more intelligent algorithm to parse and log memvar dump.
Channels try to re-connect to broker if they encounter a 1440 error within one minute of startup.
Added ability to edit FoxWeb Temporary Directory in FoxWeb Control Center.
Fixed problem is FWXCompile, which caused it to exit without compiling under certain circumstances.
Moved call to set_env at the beginning of www_read to prevent problem when date format is changed with SET DATE command (for example SET DATE BRITISH).
Improved speed of Server.ToString method for VFP 6 and above.
Response.Write does not translate "%\>" to "%>" any more.
Fixed problem that prevented correct error reporting within fw_enter and fw_exit.
Fixed problem which caused show_channels to return "No Channels Active" under certain circumstances.
Fixed problem which caused show_channels to return incorrect number of pending requests.
Auth object can handle single quote characters in userid.

Is there a list of new features / bug fixes for 2.5 yet???

This is a known problem that occurs under certain circumstances on heavily-loaded servers. The bug has already been fixed and will be released in June as part of FoxWeb 2.5.

I'm running Foxweb 2.11 on Win2k servers

I have run into this problem a couple of times since switching from FW1.x to 2.11. We have multiple channels open, say 4, I go in and check on a machine and it is only showing 1 or 2 channels in the Foxweb Channel Status window. The others don't show as busy or unresponsive, they just don't show at all. Restart channels is enabled and FW is configured in the configuration form for 4 channels, they just seem to disappear over time.

At first I thought it just wasn't showing all the available channels or something; to be honest I haven't looked very closely at the 2.x docs since we upgraded, we didn't really need the new features. Looking at this closer though this definitely affects end users, performance is really dogging when we are down to one channel and have multiple users, not to mention we start hitting frequent timeouts (no channels open).

We aren't set up for FWX pages right now, so http://localhost/show_channels.fwx isn't available, I don't know if it would show me anything that the status window doesn't.

It seems like I need to set up some kind of maintenance process to step through channels and restart them when they disappear like this.

Has anybody run into a similar problem? Any examples of maintenance processes like that?
