Hello, everybody!

Every morning I get the email from Netsight:

Netsight Critical Alarm: Device Down

Device: 192.168.251.161 (This is a stack of 5 switches)
Severity: Critical
Message: SNMP Contact Lost: No SNMP reply from device 192.168.251.161 caused by SNMP Error: Timeout [4098], last uptime was 10 Days

Could be it caused by these scripts? Especially the last one?

# Module upm configuration.#
create upm profile blackhole1
set var portb 0
set var portb $TCL(string range ${EVENT.LOG_PARAM_0} 36 39)
disable port $portb
create log entry "Port $portb blocked by UPM"
delete var portb
.
create upm profile mac_move

disable port $portb2
create log entry "Port $portb1 and $portb2 was disabled by UPM sript (mac_move), flapping MAC is $mac "
delete var portb1

set var systemname $TCL(lindex $base_list2 1)
set var systemname $TCL(string replace $systemname 0 17 {})
delete var "CLI.OUT"
#set var filename "$(systemname)_$(systemTime)"
set var filename "$(systemname)"
delete var systemname
#delete var systemtype
delete var systemTime
delete var baseSystemTime
delete var base_list2

Many thanks in advance,
