TCPIPDS1 buffer wrap on stack stack; possible data loss
Explanation: The internal TCP/IP dataspace configured for the TCP/IP component trace buffer has wrapped before the VFTP agent has processed all the records. A loss of data has occurred. This can occur in systems that are heavily loaded for extended periods of time.
Action: To avoid future data loss, increase the size of the TCPIPDS1 buffer, or increase the priority of the VFTP agent so it can keep ahead of the wrapping condition. The TCPIPDS1 buffer size is configured with the BUFSIZE parameter in SYS1.PARMLIB(CTIEZBxx). See the z/OS Communications Server IP Diagnosis Guide for details.
