Maximum number of pem files in caFiles list

In the dynamic configuration file, I have setup TLS with default stores & defaultCertificate. In the options I have enabled "clientAuthType: RequireAndVerifyClientCert". This would mean I would have to pass the client pem files in "caFiles:"

Is there a limit to maximum number of files trafik 2.0 I can provide in "caFiles:" list.? In my testing after around 430 pem files, connections starts to fail. How do I increase the limit.?

my dynamic config:

tls:
  stores:
    default:
      defaultCertificate:
        certFile: /configuration/server_cert.pem
        keyFile: /configuration/server_key.pem
  options:
    default:
      clientAuth:
        # in PEM format. each file can contain multiple CAs.
        caFiles:
          - /configuration/client1_cert.pem
          - /configuration/client2_cert.pem
          - /configuration/client3_cert.pem
.....
.....
         - /configuration/client400_cert.pem
        clientAuthType: RequireAndVerifyClientCert
