Error" exceptionMessage="Failed to acquire lock"


I met a lot of logs as follows:

genieacs-cwmp: 2023-09-10T09:38:44.433Z [ERROR] Uncaught exception; pid=70426 exceptionName=“Error” exceptionMessage=“Failed to acquire lock” exceptionStack=“Error: Failed to acquire lock\n at _s (/usr/lib/node_modules/genieacs/bin/genieacs-cwmp:2:58134)\n → /usr/lib/node_modules/lib/cache.ts:101:13\n at processTicksAndRejections (internal/process/task_queues.js:97:5)”

my environment as
GenieACS 1.2.8
NodeJS: 12
MongoDB shell version v4.4.14

Can you check and advise me to fix it

Thank you so much for your support
