< li > Judging from the time of the crash it was probably related to the Discovery indexing that starts at midnight< / li >
< li > From the DSpace log I see that eventually Solr stopped responding, so I guess the < code > java< / code > process that was OOM killed above was Tomcat’ s< / li >
< li > I’ m not sure why Tomcat didn’ t crash with an OutOfMemoryError… < / li >
< li > Anyways, perhaps I should increase the JVM heap from 5120m to 6144m like we did a few months ago when we tried to run the whole CGSpace Solr core< / li >
< li > The server only has 8GB of RAM so we’ ll eventually need to upgrade to a larger one because we’ ll start starving the OS, PostgreSQL, and command line batch processes< / li >
