For those who use OpenLog or have written code with LSI_Info:
IBM has recently told us that our open source database OpenLog that calls the function LSI_Info is not thread safe. LSI_Info is an internal debug code and cause memory issues such as heap corruption.
We have had to remove the OpenLog code from our Domino application to ensure its reliability.
I am hoping that IBM/Lotus will provide a thread-safe solution because we do rely on this code.
