[users@httpd] Core dump in Oracle HTTP Server build on Apache 1.3

Hi Folks,



Recently we are facing core dump in Oracle HTTP Server which is build on
Apache 1.3



Following is the output of httpd -V command

-------------------------------------------------------------------------------------------------------

Server compiled with....

I have tried to run the same using pstack command. Following is the output
of the pstack command

Need your help to analyze further is this issue. Need to understand the
cause of core dump and how we can fix it. Simultaneously I am also raising
this with Oracle support but not receiving any proper reply.

Sadly, pflags is not always correct.  (I think it may be related to
sig_coredump() blocking the synchronous signal upon entry, but in my
experience only customers^H^H^H^H...users can duplicate this so I haven't
played.)

A way to double check this is to look at what thread 2 is doing -- a
blocking syscall.  Those don't crash.

A best-effort way to double check that thread 1 really could have crashed
is to look what it was doing -- memcpy.

What about all the other threads?  Also blocking.

I have gone through the link
http://publib.boulder.ibm.com/httpserv/ihsdiag/get_backtrace.html
As per this following is my pflag output of core dump
---------------------------------------------------------------------------------------------------------------------------------------------------------
core 'core' of 13893: /ora10gas/OracleAS/Apache/Apache/bin/httpd -d
/ora10gas/OracleAS/Apach
data model = _ILP32 flags = MSACCT|MSFORK
/1: flags = STOPPED
why = PR_SUSPENDED
lwppend = 0x00000400,0x00000000
/2: flags = DETACH
sigmask = 0xfffffefd,0x0000ffff cursig = SIGSEGV
/3: flags = DETACH|STOPPED lwp_park(0x4,0xfdafbe08,0x0)
why = PR_SUSPENDED
sigmask = 0x0000e001,0x00000000
---------------------------------------------------------------------------------------------------------------------------------------------------------

Note that thread 2 has cursig = SIGSEGV next to it. That is the flag that
Solaris thinks did the dirty deed. Thread 2 output is as follows

----------------- lwp# 2 / thread# 2 --------------------
ff16e298 __pollsys (fdc1be68, 0, fdc1bed0, 0, 0, 0) + 8
ff109abc pselect (fdc1be68, ff1e6790, ff1e6790, 0, fdc1bed0, 0) + 1c8
ff109e34 select (0, 0, 0, 0, fdc1bf38, fe002394) + a0
fe0035d8 swwwcsl_Sleep (ea60, 7, fe012d30, 3645, fdb00200, 1) + 40
fe00470c wwccuctp_CleanupThreadProc (42bca0, fdc1c000, 0, 0, fe00465c, 1) +
b0
ff16a9c8 _lwp_start (0, 0, 0, 0, 0, 0)

So i want to understand why you are suspecting thread 1

SSLSessionCache none (or something) will avoid this code/crash, but you'll
likely encounter noticeable performance degradation (client response time
and/or server CPU).  Unless the crash is happening very frequently (i.e.,
severely affecting service) you probably don't want to do that.

You need to get assistance from Oracle.  This is a proprietary SSL toolkit
and proprietary patches to old levels of open source.
