    Two of these verbs are at a length of 1048543 (max size) and
    then a third one smaller.
    
    
    This is the indicator that this issue has occurred before
    seeing:
    ANR0443W Protocol error on session 25800 for node SOURCE
    (Windows) - invalid "memberList" field found in
    "ReplGroupMemberInfo" verb (offset 13).~
    
    Note:
    Do NOT use NOVERBCHECK server option to circumvent this issue
    because it can potentially cause crashes.
