And if I try refreshing its packages it gives below error

Hi Hamid,

No they were generating and suddenly all logs stopped generating only stdout.log is generating rest all are not getting generated at all.
I have tried restarting server several times.

Can you go to http://<host>:<port>/system/console/bundles and restart the following bundles:

org.apache.sling.commons.logservice
org.apache.sling.commons.log

com.adobe.granite.logging

com.adobe.granite.requests.logging

log4j.over.slf4j

Are you saying by default the "error.log" was not getting created ?

Can you see this logger in http://host:port/system/console/slinglog
