I often recive this kind of message. From different customers.

09/29/20 08:04:34 AM Error notified to the user awajax.lSuccess(.f.): Error detected at code line #16,249 of method 'awajax.xmlpropschangedadd' "Table could not be opened under alias" C:\Program Files (x86)\AcutMobile\Temp\5TT0YQI7C_5tt0yqi7c_main_scx_Old.DBF ANTE Call stack: 01 .processhit (561) > 02 .process (942) > 03 .routerequest (961) > 04 mobprocess.process (2783) > 05 wwprocess.process (272) > 06 mobprocess.domevent (4699) > 07 mobprocess.ajaxformrequest (4715) > 08 awajax.formrequest (9474) > 09 awajax.formrequestcomplete (9512) > 10 awajax.xmlpropschangedadd (16250)

I checked antivirus, antimalware or backup software..and if i found them i correctly configured or turned them off....

Ciao Michele,

If your app. runs with multiple COM servers, this happens usually when user reloads the page while an AJAX request is being processed:

• COM server1 builds the page and attempts to write the user's state into 5TT0YQI7C\_5tt0yqi7c_main_scx_Old.dbf
• COM server2 attempts to USE 5TT0YQI7C\_5tt0yqi7c_main_scx_Old.dbf alias ANTE to compare the user's state before and after the AJAX request.

In this case, you need to shorten the request that takes too long, and thus make sure the user will no longer want to reload the page.

You can identify this request using …/wc.wc?FoxInCloud~wFrmLogError and navigating errors until you find this one (seek server ID and date-time you see in the error message)

If your app. runs with a single COM server, then the file 5TT0YQI7C\_5tt0yqi7c_main_scx_Old.dbf is locked by another process external to FoxInCloud.
