Oracle - Arrumando o erro do EM Exceeded Max allowed Upload data no Oracle 11g

Erro:


2011-05-26 22:10:38 Thread-3161134928 WARN  http: snmehl_connect: connect failed to (myserver.com.br:1158): Conexão recusada (error = 111)
2011-04-05 23:02:09 Thread-1095002432 <Upload Manager> Exceeded Max allowed Upload data - No of files: 1588, Size of upload data: 50,048591MB, Pct(%) of Disk used: 45,54%, Disabling collections (00852)

Sintoma: Ao executar o 'emctl start dbconsole' é retornado 'failed', mas o emagent é iniciado(ps -ef | grep emagent) entretanto a interface web não inicia. 

Seguem procedimentos que realizei para corrigir o erro:

1-> Ajuste dos seguintes parâmetros no 'emd.properties':

# Comente a opção 'UploadFileSize'
#UploadFileSize=2048

2-> Remover XMLs da pasta 'sysman/upload'

3-> Adicionar na variável LD_LIBRARY_PATH o caminho para os jars do OC4J, evitando o erro:
