Hello Massimiliano, If the site is crashing on large collections, it's most likely some form of "out of memory error" being thrown by Tomcat (you'd want to check the Tomcat logs, as this level of error may not appear in the DSpace logs). My best guess is you might want to consider giving your site more memory, see https://wiki.duraspace.org/display/DSDOC6x/Performance+Tuning+DSpace
That said, this is only a guess, as you didn't provide any information about how much memory you are currently allocating to Tomcat. Additionally, as Mark noted, you should look closely at your log files. Both of the messages you sent to this list are being reported by *Tomcat* (not DSpace). When Tomcat crashes like this, you will almost always see errors reported in the Tomcat logs which provide better clues around what the problem may be.

We are using mirage 2 as theme. Now we have a problem when we try to load items only on some collection. Especially collections with large pdf (100 MB or more) and a lot of image (400 or more). The system give us this error: Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator at root@localhost to inform them of the time this error occurred, and the actions you performed just before this error. More information about this error may be available in the server error log. It seems as the system goes in time out. Do you have some suggestions? We have modified our dspace.cfg putting xmlui.theme.mirage.item-list.emphasis = file webui.browse.thumbnail.show = false webui.preview.enabled = false xmlui.community-list.render.full = false Thanks Best regards Massimiliano -- All messages to this mailing list should adhere to the DuraSpace Code of Conduct: https://duraspace.org/about/policies/code-of-conduct/ --- You received this message because you are subscribed to the Google Groups "DSpace Technical Support" group.
