Hi Keith, This is a difficult question to answer, without better understanding the reason for a system going down. It's possible the site becomes overwhelmed (either from normal behavior or a badly behaving bot crawling your site). It's also possible that your site is hitting up against memory limits & needs more optimization and/or memory.
I'd encourage you to keep an eye on the DSpace & Tomcat logs when your site becomes unresponsive. It could be that an error message appears there that could provide you with a clue -- you also may want to try and consider monitoring whether a single IP address is hitting your site excessively (which could mean there's a bad behaving bot that is bringing your site down). Finally, we do have some documentation on optimization hints/tips, if memory issues turn out to be the problem: https://wiki.duraspace.org/display/DSDOC5x/Performance+Tuning+DSpace Good luck, and let us know on this list if you notice anything more specific.
