Sinisa,

SM> This is all that mysql_ping does (on the server) :

SM>     send_ok(net);                               // Tell client we are alive

SM> No resetting of anything, what so ever.

  Ok. So if a client does only some mysql_ping() to the server with no
  queries, there will be some timeouts in net_read or net_write ?

SM> And anybody can have a bug in the code, so can you ....

  I'm   100%  agree  with  you.  I don't really understand why you say
  that. Did I let you think I said I never write a bug ?

  My  code is very small and I use to write this kind of code. I can't
  find  any bug, except if something changed in Mysql which makes that
  I'm not querying it the right way.

  To summaries the problem :

   * When compiling Mysql with "--without-debug" I have some "Warning:
   Got signal 14 from thread X".

   *  When compiling Mysql with "--with-debug" and running mysqld with
   "--debug" the server crashes with :
mysqld got signal 11;
The manual section 'Debugging a MySQL server' tells you how to use a
stack trace and/or the core file to produce a readable backtrace that may
help in finding out why mysqld died.

  * I raised filedescriptors to 1024 but it didn't change anything.

  * I tried to disable thread_cache but it didn't change anything.

  And  I  can't find any error on my code which is just connecting and
  looping for doing UPDATES to Mysql tables.

  *  I  tried  to set net_read_timeout and net_write_timeout to 600 in
  order  to  be  shure  that  signal 14 does not come from clients not
  sending  some requests to the server, but I'm getting some "Warning:
  Got signal 14 from thread X" as soon as the server runs.

  Alex.
