An older but pertinent reference is Leach and Stahl,  (1983) Nature 305
pp448-4451 " Viability of lambda phages carrying a perfect palindrome in
the absense of recombination nucleases".    The operative mutations are in
Rec BCD and SbcB.  If your strain has these knocked out  you are starting
in the right place.
