Sean, Depending on the amount of email traffic, SpamFilter should normally only use about 30-80MB or RAM. The only case were we saw huge amounts of memory used have been when the quarantined items are displayed in the quarantine list. We have had at least two reports were users have seen the quarantine tab become populated with data even after they clicked on the "Hide List" button. Can you please confirm that the quarantine tab indeed does not show any data when the memory runs that high? If the list is empty then we need to look elsewhere. What kind of email activity is going thru SpamFilter (emails/day or emails/hour, average number of concurrent incoming connections at any second)? If you'd like to, we can remote in the server to see if we see anything unusual. Roberto Franceschetti |

Roberto, I can ensure you the quarentine list is not repopulating during the huge memory usage. I will send the screen shot by email. As for the number of emails per hours: 240 connections average. I will be attempting to remove Spamfilter then reinstall this evening in attempts to correct the problem. |

We have had the same memory leak issue. We run spamfilter as a service and have found that it does not leak memory if the server's console is not logged on. It appears to be a GUI memory leak.You can logon to use the SpamFilter GUI, just log back off so there is little or no memory leakage. Also you can use terminal services or network shares to edit the spamfilter text files manually. These files are reloaded by spamfilter every few minutes, or you can restart the spamfilter service to force an immediate reload. You can not use the GUI via Terminal services or LAN shares, though. It is console bound. We (along with others) have been rallying for a serperation of GUI and service, but so far to no avail.This workaround works well for us.

I did a reinstall, with no luck to correcting this problem. As well as loggin off the consol as Micheal suggested, still no luck. I plan on installing the new build here shortly, maybe it will fix it?

Sean, The new build should not have anything new to fix the memory leak as we're not able to repoduce the problem. Again, if you'd like to, we can remote in the server to see if we see anything unusual. Roberto F. |

I have the same problem.
I looked, when the problem occured, in the "connection" screen only one connection from one sender, and the status is "RCPT TO". And the SpamFilter server getting start use the memory. From 12MB to 170MB, and I shut down the process. How can I set, tha one mail maximal size? (I use your unlicensed eval software, 1.2.0.178).

When the problem occure, the SpamFilter use not only 7 threads, it use 8 threads. And slowly eat the memory, with 100% processor. (And it's not a wrong processor to handle only one mail one time.. :-)
On the quaranten sceeen is not any mail. Currently use 450MB of memory. |

Sorry.
The sender server isn't my server.
I think, the sender resend the message, and I enable the debug view. Here is the log:>>EHLO linux.komarominyomda.hu
>EHLO linux.komarominyomda.hu
>EHLO linux.komarominyomda.hu
EHLO linux.komarominyomda.hu
EHLO linux.komarominyomda.hu

Sean, In the registered are we just uploaded beta build .192. Could you please try this latest version to see if it fixes the memory leak issue? We did find that sometimes the quarantine grid repopulated by itself, consuming large quantities of RAM is the quarantine DB is fairly big, and this build should have fixed that. Roberto |

Ok, I will try it, if I have a copy from it.
I use the unlicensed eval copy.
But I think, the problem not with the Quaranten-grid, because when sent this prblematics e-mail from this probl. server, the connection live one hour, and I cannot kill this.I think, thge problem in the SMTP implementattion.
(I don't know, this bug is the SpamFilter, or the another server, but the problem occured on my server with your sodftware.)

I think, this problem not in the gui.
I created a rule to bypass all letter to this recipient, and the log is the next: 07.31.03 12:39:59:290 -- (3720) Connection from: 195.228.227.14 - Originating country : Hungary The from server is same as that I wrote in the previous posts. I think, this server not send "normal" letter, but it shoudn't been an explaination.

We were able to replicate a similar issue with this email source, and will now work to isolate the problem and patch it. Roberto F. |

Sean, We found the problem caused by a specific message posted by Meister on this topic. A very specific malformed subject header was causing a slow but steady memory leak and high CPU. We have posted a temporary beta patch (build 1.2.0.194) in the registered user's area. Roberto F. |

After installing the first beta you suggeted, "1.2.0.192beta" our memory usage droped significatly (now only using around 75,000K) this was overnight, which before was using over 450,000K. So the change between v1.2.0.190 and 1.2.0.192beta, seemed to slow the leak (Thank You). However as you suggest, I will install the new beta 1.2.0.194 today and see if it helps even more. Thank you again! and Keep up the awesome work. Sean |
