Hello, We have questions about the TDB memory usage.
1. On some Microsoft Windows 64 bit servers, we noted that there is no mapped file used by the TDB while on other servers mapped file use is substantial. What is the trigger for mapped file use ? 2. In some cases, RAM is mostly used by the TDB. When some other applications require more RAM, the space used by the TDB is not released and we encounter memory lack issues. Despite the fact that the problem is maybe caused by a wrong memory handling done by the other applications, is there a way to limit the TDB RAM usage in order to anticipate such a blocking situation (a bit like defining the 'innodb_buffer_pool_size' in MariaDB) ? Environment: - Windows Server 2008R2 (physical machine) - Apache Jena 3.1.1 (still with this release because of the long development cycle of our product) Thank you in advance for your help. Laurent
