Hi,

If you are using contextBroker and start receiving "empty server from server" or similar errors (the particular message it depends on your development language technology, etc.). One of the causes of this problem is spontaneous corruption of the /usr/bin/contextBroker file

In order to diagnose the problem, do a "md5sum /usr/bin/contextBroker", if you don't get the following checksum, you are suffering this problem:

  *   For version 0.9.0 the MD5SUM has to be d867613160c0b8cb70fb3b24b85f616a
  *   For version 0.9.1 the MD5SUM has to be 199f211d55731c7cd30182a2e71de5b6

The solution is easy: reinstall the contextBroker package using the following commands:

# yum remove contextBroker
# yum install contextBroker

and check again that the MD5SUM is correct

Best regards,

------
Fermín
