32 bit to 64 bit migration issue RRS feed

  • General discussion

  • We have a set a of 32 bit windows services and recently we migrated it to 64 bit server by changing the build option as x64. It is being observed that the performance degraded. Also noticed that the memory utilized by this apps is not released after each execution. We have used disposed method for all database connectivity and in our apps we are using large objects ( which are holding an average of 93168 KB)

    Memory Leak


    Once we have confirmed that there is a memory leak, it's time to investigate the root problem of the memory leak. We will divide our journey to the solution in 3 phases what, how and where.

    • What: - We will first try to investigate what is the type of memory leak, is it a managed memory leak or an unmanaged memory leak.
    • How: - What is really causing the memory leak. Is it the connection object, some kind of file who handle is not closed etc?
    • Where: - Which function / routine or logic is causing the memory leak.
