Key's dat file is invalid as soon as Sparx Systems Keystore Service restarts

[monicashishodia]

Hi All

I have installed sparx key store on one of the machines but i have noticed one thing. As soon as the Sparx Systems Keystore Service restarts, the key store is not able to access key file sskeys.dat and throws error saying not able to connect to localhost. If i try to access keys, it shows empty and does not allow to add any key too.

The workaround is to delete sskeys.dat file and only then i can add same keys again, which creates fresh sskeys.dat (there is no change in hard disk or directory structure as i read somewhere while creating dat file sparx consider these two factors to generate encrypted key, to protect software from license violation).

Any idea why service restarts makes sskeys.dat invalid?

Appreciate help.

Monica
