[Nss-mysql-users] nss-mysql and NSCD

[Markus Valtin]

Hello

I recently see logmessages like:
      Oct  5 00:35:34 rs_ewam nss-mysql[4765]: client 211.53.35.250#62208: 
query (cache) 'foobar/A/IN' denied
      Oct  4 13:33:14 rs_ewam nss-mysql[4765]: lame server 
resolving 'e-burg.su' (in 'e-burg.su'?): 195.58.27.158#53
      Oct  4 13:33:15 rs_ewam nss-mysql[4765]: unexpected RCODE (SERVFAIL) 
resolving 'ns.e-burg.su/AAAA/IN': 194.226.235.22#53


My research indicates that this comes somehow from NSCD or named because on a 
other server I get a similar message from named (libnss-mysql or nscd are not 
installed).
      Oct  4 15:28:42 localhost named[5827]: unexpected RCODE (15) 
resolving 'ns2.freenet.com.ua/AAAA/IN': 195.47.253.3#53

So my Question is now:
What happened??? Is it a serious problem? Why happened? 

And what means the line: (except the obvious)
"YOU SHOULD NOT USE NSCD with this version." I did not find any information 
WHY not use nscd.

Thank you for your help

Sincerely Markus Valtin
