Summary :
After a kernel update to 4.6D patch level greater than 1078, entries related to the dispatcher's trace file (dev_disp) have been noticed, particularly indicating potential DNS configuration issues and network delays. The dispatcher performs network queries, generating warnings if a DNS server's response is delayed. These warnings are an enhancement from kernel 1078 to address frequent issues caused by improper DNS setups. The logs cannot be deactivated as they are crucial for identifying and mitigating network-related delays. For resolving these issues, refer to SAP Note 501902 for details on error handling and Note 124562 for DNS configuration guidance.
