New docs need server restart after synchronization

[galo]

Hi there,

I've been running an index on 3 nodes (master + 2 slaves) without 
problems for a few weeks, snappuller and snapinstaller run every hour 
normally, install the new index without errors etc.

In the last couple of days it seems like I need to restart tomcat for 
the new documents to appear in the slave indexes. New docs are updated, 
commited and appear if I do a search on the master, but if after the 
synchronization I search in the slaves they don't appear. If I restart 
tomcat they do.

I remember this happening while I was setting up the index and seeing an 
error somewhere (something like it not being able to open a new searcher 
if i remember well), but i'm pretty sure the configuration is ok, it's 
been working for weeks normally and I haven't done any changes since then..

any ideas where i should look at? I can't see any error messages in the 
tomcat logs or the scripts' !

thanks,
galo
