Re: [Sqlrelay-discussion] LD_PRELOAD problem

[David M. <dav...@fi...>]

It looks like the LD_PRELOAD part is working.  The:

Failed to get a cursor id.
  A network error may have ocurred.

Error is a sqlrelay client error, not a mysql error.  So I believe that
the mysql client is using the drop-in replacement library.  The
host/port/user/password may not be correct.  Double-check those.
