I recently added a 4215 to VMS for management. The 4215 has s172 on it - which I have been trying to upgrade with no success. I am trying to push out s188 to it before I upgrade it to the newest service pack, etc. The problem that I am having is that the signature update process is producing an error. The error that I am getting is: "An error occurred at the sensor during the update, sensor message = Connection failed."
I have restarted the .cids services on the sensor and tried to push the signature update to it again - to no avail. Everything else appears to be working fine and I can communicate with the device using VMS and via SSH. Is there something I can do to fix this issue? I've heard something about modifying or deleting some XML files within the sensor, but I cannot locate any documentation on it. Please offer some suggestions! Thank you for your time!
One of the common problems with an unpatched 4.1(4) sensor was that during a sigupdate the sensorApp would consume all of the sensor memory causing it to crash or hang the sigupdate. I recommend installing the 4.1(5) service pack and then update to the latest sigupdate.
