[App_rpt-users] Error: Too many open files

I usually keep connected to my hub node watching the CLI, I noticed the hub was acting weird. The screen showed the following error: "WARNING[7520]: asterisk.c:1011 listener: Accept returned -1: Too many open files" Tried looking at the log but noticed it was 750Mb. I was in the process of renaming it to view later and accidentally deleted it. Has anyone else had this error? -- boB - W5EVH
