Some SEPM logs are not forwarding to Syslog

Hi There,

I'm using SEPM 12.1.6, we did update recently, and found "insufficient disk space" logs are not being forwarded to Syslog server from which we are able to fetch the clients which are running on low disk space(because of which SEP clients can't perform updates or scans), and i verified all the log forwarding settings which seems normal. Only "insufficient disk space" logs are not being forwarded, remain all logs are being forwared to Syslog, can anyone please help me how to fix this problem? 

Thanks,

Phani.
