I am using jquery and express (maybe) project.

This project node version is 12

If I run

gulp watch

Then It work.
But after I change my script file because of editing code,

[10:47:42] Finished 'js' after 984 ms
[10:47:42] Starting 'js'...
[Browsersync] 21 files changed (artist-calendar.min.js, artist-register.min.js, client-list.min.js, contact-register-confirm.min.js, contact-register.min.js, editable.min.js, globals.min.js, invoice.min.js, login.min.js, popup-artist-confirm.min.js, popup-artist-modify.min.js, profile.min.js, staff-calendar.min.js, staff-schedule-register.min.js, studio-calendar.min.js, studio-register-confirm.min.js, studio-schedule-register.min.js, user-list-table.min.js, user-modify.min.js, user-register.min.js, utils.min.js)

Above message keep showing.

After about 2 hours, frontend is shutdown and show below error

Why it is happen and I can I solve?
