What is happening at the time of the freeze? Are you indexing?
Searching? For either of these options, what are the operations that
are happening? Is Tomcat and the Solr admin accessible while this
happens? Are there any exceptions in the logs? How much memory are
you giving it versus MySQL? I assume you're hitting both, right? Do
you have enough memory to do that? Typically DBs like as much mem as
they can get, as does Solr (for the most part).
That being said, 100K records is next to nothing, so I doubt Solr is
taking that much memory. Please describe a bit more what you are
doing and seeing.

Hi
We’re running solr on a win 2k3 box under tomcat with about 100,000
records. When doing large updates of records via solr sharp, solr
completely freezes and doesn’t come back until we restart tomcat.
This has only started happening since putting mysql on the same box
(as a source of the data to update from).
Are there any known issues with running solr and mysql on the same
box? When it’s frozen, the cpu usage is around 1-2% not exactly out
of resources!
Am i best using something else instead of tomcat? We’re still
trialling solr (presently, used for our main site search www.shoe-shop.com
and search and navigation for our microsites ). It’s an excellent
search product, but I don’t want to fork out on new hardware for it
just yet – until i know how more about the performance and which
environment i’m best to go for (win/linux).
If anyone has any suggestions/needs more info, i’d be extremely
grateful.
Thanks
Simon
