Our Ubuntu server that runs SOLR for our public websites has been brought to a crawl after we had a process hang that runs every night (to update our SOLR index). One of our techs killed the process, and ever since then tomcat6 has been using up all 8 of our CPU cores. We've tried restarting the server multiple times, and deleting unnecessary records, but to no avail. Has anyone had any experience with this? Any suggestions?

This question came from our site for professional and enthusiast programmers.

Could this be due to the leap second problem? –  Ansari Jul 17 '12 at 21:42
I doubt it. This started happening this morning at around 10:30AM EST. We've since deleted the index and reindexed from scratch, but want to avoid this problem happening again in the future. –  user1532973 Jul 17 '12 at 21:46
Can you clarify if you've stopped the java process successfully and new processes are starting up at 100% CPU, or if the same process is still running? –  Shane Madden Jul 24 '12 at 2:36
