Dear Briege,

Looking at wp logs, there is no shared memory available for work process. Hence, your instance is getting shutdown. Please increase shared memory of the server or adjust the value of ABAP parameter abap/buffersize. Then, restart the instance.

Let us know if this is helpful to you.

Best Regards,

Soham Panchal

In dev_w0 we can observe:

I Sun Nov 14 17:22:04:502 2021

I *** ERROR => shmget(10006,4701814784,2016) (28: No space left on device) [shmux.c 1508]

One of your file systems most likely /usr/sap/* or /sapmnt/<SID>/* is full or almost full. Check which OS file system is full . Clear up some space or extend space and you should be good.

Hello Briege,

The first work process that failed to start was work process 1:

****** form dev_disp

Sun Nov 14 17:22:01:728 2021
*** ERROR => DpHdlDeadWp: W1 (pid 33321) died (severity=0, status=65280, action=) [dpxxwp.c     1464]
DpTraceWpStatus: child (pid=33321) exited with exit code 255
*** WARNING => DpHdlDeadWp: W1 was inside a critical section (semaphor) [dpxxwp.c     1481]
DpWpRecoverMutex: recover resources of W1 (pid = 33321)

So, it would be better to have the dev_w1 trace.

Anyway, dev_w0 shows that the server did not have enough memory to allocate the ABAP program buffer:

O  ---PXA-------------------------------------------
O  PXA INITIALIZATION
O  ab_pbinit: System page size: 4kb, total admin_size: 352568kb, dir_size: 87212kb.

A  RABAX in run level 1

If the parameter "abap/buffersize" is not set in the instance profile, maybe set it to 800000 as a starting point.
