 Topic: Database busyPosted: 15 October 2007 at 12:52pm |

I am getting this "database busy" problem very often now and quarantine stops because of this. I am running:
SPF v.3.5.4.704 MySQL 5.0 I have nothing but SPF connected to the MySQL. Is there anything I can do? |

The latest pre-release build of SpamFilter, by popular request
 , queues all emails that are to be quarantined if the database is unavailable. When the DB comes back online, SpamFilter will insert all pending emails.

What caused it? I am interested in how to prevent this. It's not normal for a database behaves this way when only SPF is connected.

The machine is Dell poweredge 1425 with 2GB memory. I am also running a Blackberry enterprise server and websense filtering on there. It usually has 700M memory left.
I typically have 20-30K items in tblquarantine. |

I had the same sort of problems with SF v.3.5.4.704 and MySQL 4.1. On a fairly regular basis I had to stop and restart MySQL. I have found with SF 3.5.4.718 the problem has gone away. The one thing that I did do in addition to installing the lastest version of SF was modify the ini file settings for PDF scanning so I can't say for certain what has caused the problem to go away although the whole SF system seems to run a lot smoother with version 718 of SF.

I see this issue on 718.
We are using SQL 2005 Ent, on a Dual processor HP server, with 3.5gb ram.
Our volume is 400,000+ into quarantine
We have a 7 day rentention
Our current database is up to 10GB
Today we have over 210,000 Database is busy messages...
I have not research if they do get inserted later, I am concerned we are dropping them...
Is there a way to see the reason why that message is returned? Our SQL server is running 3 other small databases that work fine and the server has plenty of free memory and processor.
Thanks for the help...

Pignet,
210K errors sounds very excessive. However, some of us run SQL "Jobs" to do the expire from the DB and set SpamFilter to not do that task and I have not seen a DB Busy error since. BUT ... as I said, 210K errors really sounds like something else is going on. Curious though, what is your "DeleteExpiredEmailInterval" set to in the ini file?

Pignet -
We have almost the same setup - but receive about 750K emails a day. Our quarantine runs about 5-7GB. We keep them for 7 days too.
We had the same issues several months ago also. At that time, Roberto had me try the following settings so prevent spamfilter from doing the cleanup:
interval in minutes to delete expired items in quarantine=0
days to store quarantined emails=30
I now clean our database using sql scripts that are set to run automatically every 5 mintues.
I have not had any issues with this problem since.
If you want a copy of the scripts email me. jerbo128 - hotmail

Jeremy,
I also set the following: DeleteExpiredEmailInterval=0
This should prevent SpamFilter from doing the actual message removal (I believe) and lets my SQL stored procedure do it. My cleanup procedure runs every 15 minutes and once in a while, one of my "steps" fails but it completes the next run. I have a grand total of ZERO database busy errors over the last 30 days.

Pignet,
Did anyone get some SQL Stored Procedures to you for scheduling SQL to do the cleanup?

With Msql, we run innoDB storage engine. That helped us a bunch. Just curious are you also running innoDB and still getting these issues? |
