经过一段时间后内存耗尽

Issue details Hi there, I'm finding that browser-sync crashes because of memory exhaustion after a day or two running continuously. Here is the stack trace I get: ... [Browsersync] Reloading Browsers... [Browsersync] Reloading Browsers... <--- Last few GCs ---> [2982:0x624d7c0] 66051559 ms: Mark-sweep (reduce) 2044.4 (2081.8) -> 2043.7 (2082.1) MB, 1055.1 / 10.8 ms (average mu = 0.537, current mu = 0.018) allocation failure scavenge might not succeed [2982:0x624d7c0] 66053046 ms: Mark-sweep (reduce) 2044.7 (2082.1) -> 2044.1 (2082.3) MB, 1478.2 / 8.3 ms (average mu = 0.320, current mu = 0.006) allocation failure scavenge might not succeed <--- JS stacktrace ---> FATAL ERROR: Reached heap limit Allocation failed - JavaScript heap out of memory 1: 0xb09980 node::Abort() [gulp] 2: 0xa1c235 node::FatalError(char const*, char const*) [gulp] 3: 0xcf77be v8::Utils::ReportOOMFailure(v8::internal::Isolate*, char const*, bool) [gulp] 4: 0xcf7b37 v8::internal::V8::FatalProcessOutOfMemory(v8::internal::Isolate*, char const*, bool) [gulp] 5: 0xeaf3d5 [gulp] 6: 0xebf09d v8::internal::Heap::CollectGarbage(v8::internal::AllocationSpace, v8::internal::GarbageCollectionReason, v8::GCCallbackFlags) [gulp] 7: 0xec1d9e v8::internal::Heap::AllocateRawWithRetryOrFailSlowPath(int, v8::internal::AllocationType, v8::internal::AllocationOrigin, v8::internal::AllocationAlignment) [gulp] 8: 0xe832da v8::internal::Factory::NewFillerObject(int, bool, v8::internal::AllocationType, v8::internal::AllocationOrigin) [gulp] 9: 0x11fc026 v8::internal::Runtime_AllocateInYoungGeneration(int, unsigned long*, v8::internal::Isolate*) [gulp] 10: 0x15f0a99 [gulp] Aborted (core dumped) The machine is Linux 64bits running Ubuntu 21. I don't know if it's related, but I'm including images and reloading if they change, maybe this is contributing to exhaust the memory more quickly. The images don't change very often, however. I had core dumps disabled, I can enable them and send the dump if you need it. ### Steps to reproduce/test case See gulp script below. Just leave it running for a full day making changes here and there, it's crashed in the morning. ### Please specify which version of Browsersync, node and npm you're running - Browsersync: [2.27.9] - Node: [16.14.0] - Npm: [8.3.1] ### Affected platforms - [x] linux - [ ] windows - [ ] OS X - [ ] freebsd - [ ] solaris - [ ] other (please specify which)
