DISP+WORK Shutdown Immediately

34 Views

Dear All,

I am facing an issue from past three days on our production server. Following is the explanation for the same:

We daily take backup from OS level in the night and start our SAP server after that(this is done through windows scripts, which are scheduled tasks). This has been a practice for a very long time with out any problems. However, last thursday, after backup when SAP started, I could see that disp+work process got stopped.

Upon further investigation in disp+work log file in /work directory, I could see the below details:

---------------------------------------------------
trc file: "dev_disp", trc level: 1, release: "46D"

From the above log, it was obvious that there was some Virtual memory issue. However, we maintain the following virtual memory settings: RAM=2GB; Virtual Memory=4GB
