A virtual computer system executes a virtual computer control program on a physical computer and thereby causes guest programs on the logical partitions, respectively. The virtual computer control program includes an error recovery module to periodically recover from an error in a cache memory, an error interruption handler module responsive to an interruption notice caused by an error which has occurred in the cache memory, to recover from an error in the cache memory, and an error data initialization module to recover from an error in the cache memory with shutdown or restart of one of the logical partitions as a momentum. And the virtual computer control program conducts recovery processing from an error in the cache memory.

A connector includes a plurality of contacts. The connector includes an insulator having a plurality of through-holes for receiving the contacts. A pair of contacts are disposed in each of the through-holes. Since two contacts are disposed in the through-hole in the insulator, even if a fault occurs in one of the contacts, signal transmission in the same line can continuously be used. Moreover, since large areas of contact portions of the contacts are secured even in normal use, the capacity of electric current is increased.

New organophosphoric acid ester anhydride derivatives, more particularly new thiopyrophosphoric acid P,P,P'-trialkylester-P'-dialkylamide of the formula ##STR1## wherein R.sub.1 is an alkyl group of 3 to 6 carbon atoms and R.sub.2, R.sub.3 and R.sub.4 may be the same or different from each other and each are an alkyl group of 1 to 6 carbon atoms are now provided. These new organophosphoric acid ester anhydride derivatives have high insecticidal, miticidal and nematocidal activities and are useful as an insecticidal, miticidal and nematocidal agent.
