Semaphore 16 and ADOPCODE-3

0 Kudos

Dear all

It happens from time to time that the workprocesses in SM50 all seem to go in Semaphore 16 and Action ADOPCODE-3

I have no idea what causes this, it disappears after some seconds.

But it is quite frightning seeing all the WPs lock up

Any ideas ?

Thanks Sally

Our values for table buffer are :


Generic key 99,99 878.906 87.344 10,59 240.000 17.918 7,47 47 2.974.240

Single record 99,79 140.000 28.102 20,15 2.000 1.634 81,70 0 2.654.156

Should I increase the Generic Key Directory entries, since this one has only 7,47% free directory ?

Or do you recommedn to switch-off the automatic suppression ?

Hallo Jo,

This indicates a reorganisation of the table buffer. You may want to look at note 1311156 and also to check the buffer quality in ST02.

All the best,
