Thanks for your help Mike!
I'm not using a cluster environment and the errors happens when the
tomcat run normally.
In the server that the NtlmHttpFilter works fine the OS is Linux Fedora
Core 4 and in the server that the problems occours, ths OS is Linux
Fedora Core 5.
The two servers are 64 bits.
These are all the informations that i know for now.
How I could disabled session serialization?
Thanks again!
Sergio
