Hi Ashvin0
Yes, VSTP is configured as you mentioned
Finally I found that deleting VLAN1 from membership it solves the problem
delete interfaces ge-x//x/x unit 0 family ethernet-switching vlan Members VLAN1
Now from friday to right now it never disconnected
aromay@AGC-IDF-CORE-PR# ...hing table interface ge-1/0/8
Ethernet-switching table: 3 unicast entries
VLAN MAC address Type Age Interfaces
VLAN-CORE * Flood - All-members
VLAN-CORE 00:90:f5:e4:08:5f Learn 2:22 ge-1/0/8.0 --->notebook
VLAN-CORE 38:20:56:11:24:41 Learn 40 ge-1/0/8.0--->Cisco
