49 days is on the long side of a running program.

Memory leaks? What is the memory usage of you program when the program first starts? What is it after one day? one week? one month? 49 day? Use the Window Task manger to monitor your memory usage.

Log files. For long running programs that log, I start a new file for each new day. After a year or so if I do not clean up the log file directory, Windows file explorer is very slow when exploring the log files.

But mainly check for memory leaks. Check for opening referances without closing them.

Dear Omar,

thank you for your reply

I will monitor the use of memory

the log file is created by the builder application.

how to close it and creates a new, every day?

how to find the open reference?

thank you for your help

If I understand your logging - you are only logging every 60 sec. I would Open and Close the log file each time. 

1. Create a log file name with today's date as part of the log file name (Log_2014_07_07.txt)
2. Open log file
3. Position the file pointer at the end of the file. (Set File Position)
4. Write log data to log file
5. Close log file

The Format Date/Time String function will automatically create a new log file for each day and will reuse it for that day and then will create a new file for the next day.
