apache error:"child pid ***** exit signal bus error"

[yanxw]

Hi,I use CSWS 2.1 on alpha VMS 8.2, all patches intalled.
But my webserver is not stable,sometimes it submit sucess,sometimes it failed,I look for the error_log,found this:
-------------------------------
[Wed Feb 13 15:12:38 2008] [notice] child pid 568624367 exit signal unknown sign
al (number) (114)
-------------------------------
Any ideas?

When does this happen:
* when servicing plain HTML
* when servicing JSP, Java (Tomcat)
* when servicing PHP or Perl

What does the server log tell you?

Hi,Willem
When servicing PHP,it happened!
server log? I don't know what do you mean,I had listed the server
error_log! What do you need any more?
Thanks for your reply!

It might well be that the problem is not within Apache itself, but in the PHP module.
There are some issues with this software. I run into issues within the PHP module once in a while, that I cannot trace down:

%DEBUGBOOT-W-CHN, assign channel system service request failed
or
%SYSTEM-F-HPARITH, high performance arithmetic trap ...

Since the big part of it is a shared aimage (PHPSHR) built /NOTRACEBACK, so locating the error is virtually impossible. (The same applies to debugging PHP code) but I could track them down deep into the PHPSHR image, calling DECC_runtime routines...

I'm not using Apache so it might be that using Apache, you could get other messages.
One thing that could be the case: if the error code (114) is actually a VMS error code, it means:

%SYSTEM-E-DEVNOTMBX, device is not a mailbox

that may be related to the "debugboot' message I get (I could'nt track that message either).

I'm sorry I cannot help you further than to suggest you to log a call with HP (if you have a support contract).
