Do you notice if you are having other messages and/or callk logs disappear as well? Check the File Free parameter in Options > Status and post what you have.

yes other messages from GTALK and MSN also disappears and in File free parameter it shows 0 bytes

This is the issue. When the internal memory on the device gets low then messages and/or call logs will be deleted. There are several threads on the forums dedicated to describing how to free up memory on the BlackBerry. Search for them and follow the directions.

Here is the link to the stickied section on freeing up memory:
