Identify and address the likely causes of glibc allocator fragmentation

    XMLWordPrintable

Details

    Description

      glibc can sometimes, especially in case of multi threaded applications, keep certain pages in physical memory even though those pages have already been freed. This can be observed as increase in RSS for programs using glibc allocator.

      The goal of this issue is to identify if there are any allocation patterns in the JVM that can lead to such memory fragmentation and in turn cause increase in RSS for Java applications.
