dbmevtdisp creates lots of "zombie" processes

On all of our installation (starting with about 7.6.1 - don't remember exactly), I can see a lot of zombie/defunct proccess started by dbmevtdisp:

# ps 3346
  PID TTY      STAT   TIME COMMAND
 3346 ?        Z      0:00 [dbmevtdisp] <defunct>

# ps 22896
  PID TTY      STAT   TIME COMMAND
22896 ?        Z      0:00 [dbmevtdisp] <defunct>

# ps -ef | grep defun | wc -l
33

I have no clue why this process is started by default, the last time I logged on to the system I had > 100 defunc processes.

Is this problem of those "zombies" known?

Hello Markus, Thank you for the update.

According the provided by you information your case is known and reported in PTS 1151090. The issue planned to be fixed as of database version 7.6.05.01.

In your case the internal Event Dispatcher was active (auto_update_statistics was on) and events were being dispatched.

If you have the auto_update_statistics on in your dabase, please check time to time if

Event Dispatcher zombies (defunct processes) show up in process overview, then you could use the workaround before the database will be updated.

Please review the information in PTS at www.sapdb.org/webpts -> search by given number 1151090.

Regards, Natalia Khlopina
