Most of the dialog processes cannot be started.

It's a good chance that there is a lack of memory.

How much RAM and swap there are on the server?

Please try increasing swap/RAM if you have spare.

And please check ST22/SM21/ST02.

Dear Suresh,

on your screenshots I see, that work processes are waiting for semaphore 33, semaphore 33 means (note 33873 - What do the semaphores mean?):

33: ES-Semaphore            (memory management, extended segm. admin)

You have to check ST22 for memory dumps, ST02 how much memory was allocated and traces in work directory of the instance, if any errors for memory management are reported.

Hi Sunil,

We have any changed any parameters recently. Please find the attached dev_disp and dev_w0 .

Server is working perfect after the restart but after 2 or 3 days we are facing the same issue.
