Mailscanner loops stops processing emails.

[Richard Mealing]

0.98.1_1

I tried using the .3 version but it doesn't compile for me either. I'm waiting for the .4 version to become available in the freebsd ports. I'm not sure it's going to fix my problem through.

I would say it's a permission problem but it works most of the time, so could it be? 

When I get a heavy load like a ddos or something, it breaks. Clamd crashes and then restarts, processes some mail but then crashes again. Since I changed the Processing db to 0 I don't get this loop any more, so I'm happy now, but I really want to try and fix the clamd crashing problems.

I will continue to debug clamd. 

Thanks,
Rich

clamd ???  :)  What version ?

I'm still using  0.98.1 because 0.98.3 is buggy

There is 0.98.4.rc1 which I can't compile

| Hi Martin,
|
| Thanks, but that doesn’t work for me.
| I changed the Processing attemtps to 0 and now I see clamd timing out and crashing in the logs.
|
| Lots of this -
| MailScanner[66580]: Virus Scanning: No virus scanners worked, so message batch was abandoned and re-tried!
|
| Lots of this –
| MailScanner[71612]: Cannot find Socket (/var/run/clamav/clamd) Exiting!
|
| My socket does match mailscanner..
|
| But now all the emails seem to be processing and obviously now not being quarantined my mailscanner.
|
| I’m debugging clamd but I can’t find anything obvious in the logs. I’ve opened a thread with the clamd list.
|
| Here’s some of my clamconf –n -
|
| LogFile = "/var/log/clamav/clamd.log"
| LogFileMaxSize = "104857600"
| LogTime = "yes"
| LogVerbose = "yes"
| PidFile = "/var/run/clamav/clamd.pid"
| TemporaryDirectory = "/tmp"
| LocalSocket = "/var/run/clamav/clamd"
| MaxConnectionQueueLength = "30"
| MaxThreads = "50"
| ReadTimeout = "300"
| CommandReadTimeout = "7"
| MaxQueue = "300"
| Debug = "yes"
| User = "clamav"
| AllowSupplementaryGroups = "yes"
| StructuredMinCreditCardCount = "5"
| StructuredMinSSNCount = "5"
| MaxRecursion = "20"
|
| Here’s my mailscanner processing timeouts –
|
|
| Max Unscanned Bytes Per Scan = 100m
| Max Unsafe Bytes Per Scan = 50m
| Max Unscanned Messages Per Scan = 30
| Max Unsafe Messages Per Scan = 30
|
|
| I’m wondering if there is something here I need to change. Any advice would obviously be appreciated!!
|
| Thanks,
| Rich

|
| make sure the MailScanner perl script has the -U flag at the top, sounds like the usual taint mode issues.

| Hi,

| I’m having problems with mailscanner where I see the error like - Quarantined message s4K962Jg091731 as it caused MailScanner to 
crash several times
|
| Here’s my debug –
|
| mailscanner --debug
|
|
| In Debugging mode, not forking...
| Trying to setlogsock(unix)
| Building a message batch to scan...
| Have a batch of 30 messages.
| Can't call method "CombineReports" on unblessed reference at /usr/local/lib/MailScanner/MailScanner/MessageBatch.pm line 736.
|
| I cannot see any problems with permissions, but I will be glad to share them with the list. Just let me know what you want to look 
at.
|
| The only thing that seems to fix this is deleting the Processing.db file for mailscanner, then restarting mailscanner. If I have a 
large queue then it just happens again and I start seeing “Making attempt 2 at processing message s4K9YVUO015387” etc etc.
|
| Does anyone else see this problem or is it just me?
|
| MailScanner-4.84.6
| sendmail-8.14.5
| clamav-0.98.1_1
| FreebSD 8.2-RELEASE
|
| Thanks,
