 It looks like, that noone else has this kind of error - got no response so
 far. The reason could be that my server uses shared memory - not very large
 segments (maybe 10 segments each 64kB size). But these pages will be used
 very often: A Server process is adding data to the segments, and many
 clients hang on a semaphore and wait to read the new data. Each segement
 contains "a lot" of (so called) rows.
 Maybe next evening I could write a "stress test" dummy client/server, to see
 if I could reproduce a crash.
 With the current "4.7-STABLE" my machine crashes each day ... :-(
