Scalix Forums

Hello,
I am getting the followin error:

ERROR Local Delivery(Local Delivery) Mon Jul 24 23:50:14 2006
[SYS 22] Invalid argument
Pid of logging process: 21510
Current errno value: 22
Last Msg Id: 10140335.1153809682
Last Msg DirectRef: 0012e574b5c00203

It's not very clear what that means. Anyone?

The same thing here with inbound messages (latest Scalix version on Debian):

ERROR Local Delivery(Local Delivery) Thu Feb 22 18:37:32 2007
[SYS 22] Invalid argument
Pid of logging process: 23355
Current errno value: 22
Last Msg Id: 45DDC74A.40002(a)DOMAIN_REMOVED
Last Msg DirectRef: 00012000ac0914b7

Despite this error, the message gets delivered.

What is the reason for this error? Any hints how to solve it?

Thank you & kind regards
Stephan

Some more detail would be helpful:

Does this occur for all messages delivered?
Does it occur only for delivery to certain users' mailboxes?
If it is only certain messages do they have anything in common?
Is there a stack trace in the error log for these errors?

Thanks - Richard

Hi Richard,

thank you for your reply!

To answer your questions:

As far as I tested by now, it hits all messages delivered to local accounts. There is no difference, if the mail comes from an external user or via webmail from an internal user.

I have checked two users who are the only users in my testing environment and it happens to both of them. I tried sending using different mail clients, too - no difference.

catalina.out does not log any error.

Thank you, kind regards
Stephan

Update:
The following details I found in "Lokale Mailzustellung" in the /sac:

Hi Stephan,

From the error stack trace I can tell that local.delivery is having a problem in accessing shared memory. Can you tell me if the problem persists after you restart local.delivery:

If it does persist can you try restarting Scalix completely:

Does it still happen after restating Scalix?
Regards - Richard

Hi Richard,

I just checked your two suggestions, neither of them solves the problem, the error remains.

I have attached the Stop/Start output.

Thank you for your help,

kind regards from Germany
Stephan

OK, so it seems to be a persistent problem with shared memory.
What do get when you run the ipcs -m command?

For a Scalix 11 system (RHEL3) I get:

Hi Richard,

I see

I think the EINVAL (errno = 22) might be a red herring because the code looks as though it might be attempting to detach an invalid pointer at the point of failure. Which is a pity -- it would be nice to know the real reason for failure -- it looks as though a call to shmat() is failing. There might be a way to find the real error ...

While I'm thinking about that though can you tell us what's in each of the /proc/sys/kernel/shm* files -- the usual cause of shared memory failures is lack of resource somewhere. What version of the kernel (uname -r) are you running? And which Debian release?

We might be able to find the actual error. Please bear with the instructions as I tried this out on a 64 bit machine (running 32 bit Scalix!). We want to put the local delivery process into an aborted state so we can start it "by hand" under strace so try this:
Check that the error is reported by omshowlog and then do the "kill" command again. If you grep for "shm" in /etc/ld you should get all the sys v shared memory calls including, vitally, the value of errno for any that failed. Just showing us the output of "grep shm /etc/ld" would be useful then we can might be able to tell what's going on.

Hi,

sorry for delay.

I did some further tests on my system and installed a second machine running scalix.

The problem seems to be related to the grsecurity extensions I compiled in the kernel. On the second system I tested, the licensing daemon did not work (segfault). After disabeling grsecurity, everything worked fine, so is disabled it on the first machine and now everything is fine here,too.

If you want to track this issue and need further information, please do not hesitate to contact me.

Thank you for your excellent support in this forum!

Stephan

Stephan,

not sure and I don't think we're planning on supporting this environment anytime soon, but out of personal interest, did grsecurity add an entry to it's audit logs about what our processes were trying to do and was blocked as a result of them being there?

Florian.
