java.lang.OutOfMemoryError: Java heap space

[kase]

Hi!

I running "Alfresco-Community-2.1R1" on Suse10 with 1 GB RAM and I try to copy a bunch of file via windows explorer and after a while I get error.
On tomcat/logs/catalina.out the error message is:
10:28:41,625 ERROR [alfresco.smb.protocol] Closing session due to throwable
java.lang.OutOfMemoryError: Java heap space

Do I need to install more RAM or anything else?
Thanks for your help.

How much RAM have you actually assigned to the JVM? If you installed Alfresco from a package it will probably be given 512MB - if you just added the WAR file to tomcat yourself then it will probably only be given 64MB which is not enough! Also you may want to use MySQL or similar rather than the default of HSQL. We don't know of any CIFS performance issues related to memory leaks so it's probably just a case of giving the JVM a little more RAM to play with.

Thanks,

Kevin

Total I have 1 GB RAM installed and 512 MB is assign to Java, I incresed it to 700 MB and now I don´t get the error message but it still slow when I browse the folders with windows explorer.
If I have about 50 GB of data, how much RAM do you recommend?
