It turned out we were running 3.0.6 version (even though we pulled from the 3.0.8 link a bit ago). Now that we re-compiled with 3.0.8 it appears to be fixed, was the below code changes what caused it? 

Something to do with not using my_bool originally?

int retn = 0, x, reconnect = 1;
mysql_options(RaMySQL, MYSQL_OPT_RECONNECT, &reconnect);

my_bool reconnectbuf = 1, *reconnect = &reconnectbuf;
mysql_options(RaMySQL, MYSQL_OPT_RECONNECT, reconnect);

Well the earlier rasqlinsert.1 code does have a problem that the new one tried
to fix.  I’ll try to see what may be up with mysql_real_query() error messages,
and see if we missed something there.

But in the OP, the problem is that rasqlinsert.1 is running, but not updating
the database, in this second report, rasqlinsert.1 is failing ??

I am seeing something similar with Netflow data processed by Radium (labels added) and rasqlinsert reading the processed radium data from port 561. In my case the rasqlinsert process dies without any error messages (it is built with .debug and .devel) It isn’t practical for me to enable debuigger output since the failure can be many hours into the run.
The one clue that I do have it that the release candidate set (3.0.8-rc1) worked fine.
I haven’t had time to do much more than go back to the working release.

Hey John,
rasqlinsert() is multi-threaded, and its possible that
the cache concurrency thread, the one that is managing the
database cache, exited if the database fails.  
rasqlinsert() should close, if that thread is done.
So you are seeing rasqlinsert() is still running, but
not updating the database ??  Is rasqlinsert() getting
bigger ???  (should be generating INSERT and UPDATE 
requests, but the DB thread is not processing them ???)

I was wondering if it’s normal behavior for rasqlinsert to cease inserting netflow into the database if the connection becomes interrupted? It seems if the mysql database is restarted or any part of the connection between rasqlinsert and the db is broken, it will not attempt to re-connect and continue flow insertion.
