KimHJ Comca Systems, Inc | I get this error on my web server sometimes, mostly a few days after I have it restarted. All my modules and programs are set to AutoSessionName := True
Any idea how I can fix it? I have to restart EWB server for it to work. Thanks, Kim |

These errors usually indicate bugs in code - usually locking related and/or things like long running operations etc. Key is to identify where exactly this happens and then narrow it down to source.

Raul<< Yes using EDB. There is no long running operations, except I have a program running with a timer that every minutes check if any new records are added to the database, but that have been running for months. Then I have three modules. So it could be the module is trying to access a record that is locked by another process? Thanks, Kim |

There is not enough info here to say for sure what it is going on exactly. Can you extract the actual content of the error - the string part of the error message and also try to do some logging in your program and modules to pinpoint where and how exactly this is happening. Things i would personally check 1. Program that runs on timer - local or remote connection ? Any chance that logic is not handling errors properly and for example running next poll if previous poll is timing out still or such ? 2. Modules - generally check they are properly multi-thread aware - i assume this is OK since it runs fionr for a while. See that modules are properly handling error/exception by cleaning up and not leaving locks hanging etc. Raul |

The error is: Can't create Session ID:1 That is why I wrote that I have all the session set to autosession. Kim |
