Description

After installing Snort and starting the service on an interface, fails to start and the following is reported on the system logs:

Feb 18 19:21:06 hostname snort[5625]: Commencing packet processing (pid=5625)
Feb 18 19:21:13 hostname kernel: pid 5625 (snort), jid 0, uid 0: exited on signal 10

on another SG3100 when trying to replicate the issue, it shows:
