CMIS errori

[fedemori]

Buongiorno, presso un cliente ho installato la versione 4.2.c di Alfresco.
Alfresco viene chiamato attraverso un'unica sessione con CMIS. Il servizio funziona correttamente ma nel file alfresco.log si verificano spesso i seguenti errori.

Attualmente il cliente ha potuto darmi come server solo un Windows 2003 R2 32 bit, quindi ho potuto dargli solo i seguenti parametri al servizio di windows:

-Xms1024M
-Xmx1024M
-Dalfresco.home=C:\Alfresco
-Dcom.sun.management.jmxremote
-Dcatalina.base=C:\Alfresco\tomcat
-Dcatalina.home=C:\Alfresco\tomcat
-Djava.endorsed.dirs=C:\Alfresco\tomcat\endorsed
-XX:MaxPermSize=256m
-Djava.io.tmpdir=C:\Alfresco\tomcat\temp
-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
-Djava.util.logging.config.file=C:\Alfresco\tomcat\conf\logging.properties
-XX:+UseConcMarkSweepGC
-XX:+CMSIncrementalMode
-XX:CMSInitiatingOccupancyFraction=70

Per gli indici utilizzo Lucene con le seguenti configurazioni:
dir.indexes=f:/Alfresco/alf_data/lucene-indexes
dir.indexes.backup=f:/Alfresco/alf_data/backup-lucene-indexes
index.subsystem.name=lucene
index.recovery.mode=AUTO

Ciao,

hai qualche informazione in più? Ad esempio:
l'errore è solo visibile nei log o impedisce il funzionamento del client?
Riesci a riprodurre l'errore o viene fuori in modo random?
Il client è un tuo sviluppo custom?

Ciao l'errore si verifica solo nei log e non sul client, ed è random. Il client ha Installato Alfresco Community 4.2 sul quale ho inserito delle classi documentali custom e un client CMIS che ho creato io
