    Hi,

    What it interval of you WDT? How do you have set timeouts for DNS ( sl_NetAppSet(SL_NETAPP_DNS_CLIENT_ID, SL_NETAPP_DNS_CLIENT_TIME,..)?

    Please make sure that this two configuration are not in conflict.

    Hi,

    what is the parameter SL_NETAPP_DNS_CLIENT_TIME mean?

    This is a way how to set timout for sl_NetAppDnsGetHostByName() function. In case you have set long timout, it can cause WDT reset because sl_NetAppDnsGetHostByName() is a blocking function. Additional information about this API you find at SWRU455 chapter 6.6.

    what append if two task call the function sl_NetAppDnsGetHostByName in the same time?

    I don't expect any issue.
