Which method do you use to index? If you are using SolrJ you can use the
streaming update server
it is a better option for the solr server, because the server does not
need to held it all in memory.

(if you are using the post.jar file there was bug which causes OOMs but
I didn't remember exactly ...)

then, when the solr server crashed, it cannot remove the lock file. if
you are sure there is only one indexing process you could specify remove
<indexDefaults>
   <lockType>native</lockType> <!-- or any other possible too ?? -->
   <unlockOnStartup>true</unlockOnStartup>
</indexDefaults>
