Subject [users@httpd] 2.0.44/prefork Invalid argument: connect to listener, then crash
Date Mon, 17 Feb 2003 17:46:40 GMT
As of 3 days ago, my apache went belly up. I'll get to exactly what 
happened right after i drop my ap info:
Apache 2.0.44 w/mpm prefork
on openbsd 3.2, pent. 133 (i believe), 64m ram
mods included: so, and php 4.2.3
and standard conf with only addtype and load for php

Ok, heres what happened. Server was running fine for 29 days, no 
hickups, smoothly, then, one morning, it stopped responding. I tried 
restarting it, but the 10 httpd process wouldnt go away, tried kill for 
each of the pid's and all i got was a response that they didnt exist.
Checked my error logs, every second, for about a few hours, was the 
following error:
[warn] (22) Invalid argument: connect to listener
about half way through that, there was a connection or 2, but the server 
pretty much called it quits after that. So i decided to check a bit 
above, just usual crap from codered, etc, but right exactly above the 
start of the invalid argument was an error:
[error] [client xxxxx] client sent malformed Host header
In the access log, i got what the header was that corresponded to that 
error:
64.167.18.138 - - [10/Feb/2003:18:31:36 -0500] "GET 
/default.ida?NNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNNN%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u6858%ucbd3%u7801%u9090%u9090%u8190%u00c3%u0003%u8b00%u531b%u53ff%u0078%u0000%u00=a

  HTTP/1.0" 400 326

I've seen that before in my logs, but apache never responded to it 
before, especially with a malformed header error, normally just gave a 
404. But anyways, so i finally got to the point of having to restart to 
get everything to clear up. Apache worked fine after the boot, running 
nicely, till yesterday morning, when it completly stopped again, and 
same symptoms of not being able to close any of the running processes.
One thing i did note, was, the previous error_log was 1.3 megs, so i 
coppied it to my computer here, and deleted the original, to start fresh 
  from the previous logs, you know, just to watch for apachy being 
weird. Well, after that reboot, apache never created the log again like 
it has in the past, and in the 24 hrs it was running till it died again, 
still hasnt generated it.

Oh yeah, one more thing i noticed, when i ran ps -ax to see all the 
processes, normally apache after boot lists as httpd -k start, or 
something to that effect (i really don't remember what exactly it is), 
but after the times it has crashed, it just lists as (httpd), and each 
of thoes, lists like the following output:

USER       PID %CPU %MEM   VSZ   RSS TT   STAT STARTED       TIME COMMAND
nobody   29198  0.0  0.0     0     0 ??  ZW    -          0:00.00 (httpd)

Everything is set to 0, so something is hickuping somewhere, and i have 
no idea whats going wrong. I've waited a few days before posting to here 
just so i could look around and make sure it wasnt something stupid I 
did, but I can't find anything.

Any help would be appriciated, and if anyone needs more info, i'll help 
as much as i can.

Thanks,

Pete Rippe
