[K12OSN] ooo 1.1.1a & complex xls table crashes

["mella" <mellax pm ee>]

Hi!

I found reason why sometimes my client's ws just rebooting. 
If they open complex excel table with 000.org, it restarts every time
just in same place. If user save this XLS to native OOO format, all
working OK.
And also it happens when in user's mailbox (Mozilla 1.6-1.0.0) appear
big attachment.

In /var/log/messages every time I found following messages:

Jan 30 11:20:35 ts gconfd (jaanm-31071): Received signal 15, shutting
down cleanly
Jan 30 11:20:35 ts gconfd (jaanm-31071): Exiting
Jan 30 11:20:37 ts gdm(pam_unix)[30808]: session closed for user jaanm
Jan 30 11:20:37 ts gdm[30808]: gdm_slave_xioerror_handler: Fatal X error
- restarting ws239.ltsp:0

Very strage! Log show that user exited cleanly :)

Server FC1, K12V4, 4G RAM.
Client C300/64MB RAM.

Maybe I also must enable swap over NFS for workstations?
