solr service shut down for no apprent reason

问题

I'm using the solr5.3.1 for full text searching.And I'm using PHP with solarium library to communicate with solr service.It is doing well in most of the time.But it was shut down twice for no reason.I check the log files,and find no error message.So I was curious to know is there are some reasons will cause solr to shut down itself? I can show you more detail information if you need to help me solve the problem,just tell me in the comments.Thanks so much!

Thanks for @MatsLindh's comment! I checked my syslog(/var/log/messages),and found this Out of memory: Kill process 23076 (java) score 49 or sacrifice child.JVM was killed because of OOM.

now, I run echo -17 > /proc/{solr_process_pid}/oom_adj to avoid solr process being killed again.
