Hi All,

sas sasserver1_1 is crashing down everyday (we are restating everyday manually then SAS EVM  working) .

what could be the reason for shutting the sasserver1_1 service down. 

Thanks,

SS

Maybe you can find error messages in the log-files. Have you checked them?

SS,

When SASServer1 crashes it could be one of dozens of causes: out of Java Heap, out of Disk Space, problems in the SAS Code, someone stopped the servers from the command line, and many many more.  I would start by looking in the 'server.log' and 'catalina.out' logs found here:

.../config/Lev1/Web/WebAppServer/SASServer1_1/logs/ 

Look for errors around the time the server fails each day.

A nice SAS Note for log locations is here: http://support.sas.com/kb/55/426.html 

If the logs are not helping I would try opening a support track with us.

Thanks,

its a memory leak, changed the memory settings .

Thanks,

This is far more likely to be the cause - http://support.sas.com/kb/58/589.html

Which value did you change?

[sathya66]

It is in setenv.sh file ( JVM_OPTS to 8GB) and also we increased the insatnce memory .

[wernermaes]

JVM_OPTS="-Xmx4096m -Xss256k -Xms2048m -XX:+UseG1GC -XX:MaxGCPauseMillis=500 -XX:+DisableExplicitGC -XX:ReservedCodeCacheSize=96m

I suppose you mean increasing maximum heap Xmx to 8Gb?

[sathya66]

yes, but in my settings Xms has the same value as Xmx
and also check the memory(used ,avaiable,etc) usage on your insatnce(free -g) , it could be one of the reason for memeory leak.
