Webproxy needs to be restarted every day

Hello, I am running VyOS 1.4-rolling-202110020217 sagitta. I have a webproxy configured and it works fine, but I have a problem: webproxy service stop working suddenly and I have to restart it every day.

I have increased the cache size from 100 to 1024, but the trouble is not solved. What can I do? this is my configuration, thanks in advance:

# show service webproxy
 cache-size 1024
 default-port 8080
 listen-address {
 listen-address {
 url-filtering {
     squidguard {
         default-action block
