Estou tendo problemas de memória com uma instância de escravo Solr.
O problema é que toda vez que o escravo replica novas mudanças do mestre, o escravo inicia um novo buscador e, aparentemente, o antigo não é liberado.
Eventualmente, a coleção jovem está cheia e ela aparece na coleção antiga (ou pelo menos é assim que aparece) e começa a fazer constantes coletas de lixo completas. Ele não parece realmente ser capaz de liberar qualquer memória perceptível neste momento. As coletas de lixo completas podem fazer com que pesquisas que normalmente demoram alguns milissegundos sejam executadas, levando de ½ a 4 segundos em picos a cada 10 segundos.
E novamente, em algum momento, até mesmo a velha geração está cheia, e então ela pára tudo, e consegue liberar alguma memória, ou apenas parece travar completamente, aparentemente para nunca mais voltar a ser funcional.
Algumas informações do sistema:
A máquina é uma máquina do Amazon AWS m1.medium:

o item spm-monitor é um sistema de monitoramento da SemaText.
O Solr tem 4 núcleos, 1 para cada um dos 4 países, e contém informações sobre o produto. 3 dos núcleos têm uma pequena quantidade de documentos, mas o 4º tem cerca de 470.000 documentos. O índice desse núcleo atualmente ocupa 843MB.
Aqui está o meu solrconfig.xml: link
E meu schema.xml: link
Eu uso pastebin porque senão esse post seria muito grande.
Veja como uma saída de jstat -gc [pid] 2s
procura vários eventos:
Quando o solr é iniciado, ele é executado corretamente e todas as consultas levam o tempo normal:

Eu também tenho um dump do heap de uma das vezes em que ele parou de ser capaz de responder às buscas, então se alguém quiser alguma saída de jhat
eu posso fornecer isso.
Alguém tem alguma idéia de por que o solr / tomcat / java está fazendo isso? Eu posso replicá-lo consistentemente, então se você precisar de mais informações de depuração, eu posso fornecer isso também.
