I really did like the VMS (open is silent) debugger, it knew all about context :)

Oh, I see myWilliams confusion. You were using 'list' which isn't sensitive to the thread context. so all those threads weren't in the same routine.
Could you run the 'where' ncommand in each thread, that would be very useful !!!

Looks like every thread is in the same routine, trying to deal with a queue ... hopefully not the same queue, but possible, and that would be a bug . Sorry if this is inconvenient, but could print out the queue in each thread. Looking at this now.

Subject: Re: [ARGUS] rasqlinsert disconnect issues
so thread 21287 complains about the mysql error, and thread 21300 is trying to sort the queue. I suspect that 21287 is exiting or has exited, and 21300 is unaware that the sql 'backend' has raised the done flag.
can you type 'where' so we can see which thread is dumping ??

Carter,
I’m running rasqlinsert using –S localhost:561 to process the output of radium which is doing labeling. I’ll fire up an instance of the release code with the same parameter but a different table name and see if there is anything obvious. I’ve built the release code with both .debug and .devel do you have a recommendation for a debug value?

Hey Dave,
Well, that’s not what we’re striving for, so
if we can capture what that is all about, I’ll
fix as soon as I can.

The running but seems to no update the database was a problem that I reported and you fixed in one of the very last release candidates. The current 3.0.8 does not have that problem as best I can tell but it does stop after between 8-20 hours with no log messages that I have been able to find.

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 ??

Carter,
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 ???)

Hello,
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.
Thanks!
John
