[Using Sakai] Problem with Sakai access

[Juan Pablo Romero Bernal]

Hi,

I'm using Sakai 2.5.4 six months ago without problems. However, some
days ago i get this error (in /portal):

Session
session: ${s.getId()} user id: ${s.getUserId()} enterprise id:
${s.getUserEid()} started: ${s.getCreationTime()} accessed:
${s.getLastAccessedTime()} inactive after:
${s.getMaxInactiveInterval()}
tool session: ${ts.getId()} started: ${ts.getCreationTime()} accessed:
${ts.getLastAccessedTime()}
Unknown Request
Snoop for request
${req.toString()}
Request headers

Servlet parameters (Single Value style):

Servlet parameters (Multiple Value style):

Request Attributes:

I've been checking the tables SAKAI_SESSION, SAKAI_EVENT looking for
errors, but nothing. I've tested with a clean database and Sakai
works.

Any idea ??

Bye,
