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

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

[Jaideep_Brar]

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

Hi jbrar, Even i faced similar issues, After restarting the above bundles logs started working. But this is happening quite frequently, may i know root cause of the issue and let me know if any configuration changes has to be done please.

Please log a daycare , share log files and we can check whats going on.

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.
