Hi Christian,
sdb 17760282 1 0 Nov 11 - 5:44 /sapdb/KWP/db/pgm/dbmsrv -P 0000000a0000000d0000000e00000011
If you look at the timestamp of above process it is running since Nov 11. Haven't you restarted your database instance since Nov 11 ?
If the answer is YES, you may blindly kill this process as it zombie and will not harm your running instance.
