I believe this to be the same issue we resolved for our 9.1 compiled applications on Server2008 using Citrix/RDP.
We put additional copies of the executables(s) on each of our Citirx server's local drives. No problems since we did this, and we weere having major problems for a while. I don't remember the exact wording but my internet searches trying to resolve this issue referred to a known Windows issue about only one Control block (MCB?) and once locked by a crashed program, all users would attempt to connect through the one locked/crashed MCB (or whatever it was called) file. We have 40 Citrix users working constantly entering sales orders and checking stock etc. We are very happy with how things are working now.

Problem appears to occur only on RDP sessions on a Win 2088 terminal server. Application will run fine for a day or more and then a problem occurs. When the problem occurs no R:base session, RDP or workstation, can attach to the database files. Stations already attached appear to hang, the application stops working. The problem can be solved by rebooting the terminal server (the file server and workstations do not need to be rebooted). I believe that the problem can also be solved by clearing the open file connections to all R:Base sessions originating on the terminal server without actually rebooting the server, but I'm not 100% sure of that. After the problem is solved, all users can access the database again without requiring a reboot of the file server. The files are intact, except that operations in progress may have left cursor or row locks on tables that cannot them be cleared. In other words, it appears that one of the sessions on the terminal server is obtaining some kind of lock on one or more of the database files that is affecting both new and already existing connections to the file(s). QUESTION: For those users seeing something similar, are you running with STATICDB on? I'm wondering if that setting would cause fewer locking issues, at least on RB1. -- Larry _____ From: John Engwer <[email protected]> To: RBASE-L Mailing List <[email protected]> Sent: Wednesday, January 18, 2012 10:09 AM Subject: [RBASE-L] - RE: Application "hanging" Dennis, I am seeing a similar problem with my V8 application running MS server 2008. (users local on Terminal Services, RDP). The application will intermittently hand and post a "Cross-Thread error" in the OS event log. The application is fairly large and the hangs can occur anywhere in the application. If you search the list you will see my prior postings on this subject.

Running slowly but usually OK. Occasional "Application Hangs" are an issues. In this environment the server is just pushing screens and printouts to client and receiving keyboard/mouse input. Is this the same as a timeout? TIA, Dennis ***** Dennis Fleming IISCO www.TheBestCMMS.com Phone: 570 775-7593 Mobile: 570 351-5290
