strident.silence

Hi, I seem to have issues with the queries not returning results (which was returning some 10 seconds before). For example, I have this query select SMS_Package.PackageID, SMS_Package.Name, SMS_Package.Version, SMS_Package.PkgSourcePath, SMS_Package.StoredPkgPath from SMS_Package where SMS_Package.PackageID like ##PRM:SMS_Package.PackageID## order by SMS_Package.PackageID which returns SMS_Package information based on user input in Config MGR. If I enter "%0000A", I get one result. For no reasons not known to me, if I rerun the same query I might not get anything. This behavior happens with all other queries. Is this a known issue, or am I missing something? Thank you
