Segmentation fault on confd_val2Str

Getting segmentation fault as shown below (Using confd 7.4.1).

Would appreciate any inputs/suggestions on what would be leading to this.

Thank you in adavance.

You likely did not load the schema before calling confd_val2str(). See “Using Schema Information” in the confd_types(3) man page for details.

if (confd_load_schemas((struct sockaddr*)&addr,
                         sizeof (struct sockaddr_in)) != CONFD_OK)
    confd_fatal("Failed to load schemas from confd\n");

Hi Cohult,

Thanks for reverting back.
We are loading the schema using confd_load_schemas API.

Just an additional note, if we reduced the number of subscriptions then it works fine.

Since the number of subscriptions and confd_val2str() is not related, are you out of memory somewhere? Or did you overwrite the memory holding the schema that confd_val2str() use?

The issue was at our end.
Thank you.
