IPS (SSM-20) on ASA 5540 gets unresponsive everyday!

IPS comes up when I issue hw-module 1 reset command. This has been so annoying and I still have not established what causes this.
I was using 60 day demo license that has currently expired but according to Cisco documentation the sensor should work perfectly only the signature updates will not happen. Besides the problem was occuring even before the lisence expired.
