Hi, We have hints on how best to performance tune DSpace 6 (including how much memory to allocate, etc) in our documentation at https://wiki.lyrasis.org/display/DSDOC6x/Performance+Tuning+DSpace
Hopefully that'll give you some hints to go on, based on the type of "crash" you are seeing (you may want to check your DSpace & Tomcat logs around the time of the crash to see if it's crashing because of a lack of memory or some other reason). If you need more help, let us know on this list. However, it would be helpful if you check your logs as it's otherwise impossible for us to determine the root cause of the crash. It could be an out of memory error, an out of disk space error, or something else entirely. See the Troubleshooting guide for hints on finding errors in logs: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error Tim ________________________________ From: [email protected] <[email protected]> on behalf of Henry Atsu Agbodza <[email protected]> Sent: Tuesday, September 6, 2022 1:28 PM To: DSpace Technical Support <[email protected]> Subject: [dspace-tech] DSpace 6.3 Frequent Crashes Dear all, my DSpace 6.3 on Ubuntu 20 LTS using tomcat 9 in /opt/tomcat/ is crashing frequently. I uninstalled tomcat 8 and installed tomcat 9. A check on Control panel shows the following: Max Memory is 6010 MB Allocated mem is 785 mb Used mem is 678 mb Free mem is 106 mb [mem1.PNG] Unlike tomcat 8, I don't know where exactly to put in settings for tomcat 9 in /opt/tomcat/ . My Server however has a total memory of 24033 MB. The server is dedicated entirely to DSpace. [mem2.PNG] What are the settings i need to implement to optimise memory usage to prevent the crashes. What are the commands to run? Any other suggestions to prevent the crashes will be deeply appreciated. Thanks in advance. -- All messages to this mailing list should adhere to the Code of Conduct: https://www.lyrasis.org/about/Pages/Code-of-Conduct.aspx --- You received this message because you are subscribed to the Google Groups "DSpace Technical Support" group.
