AH00052: child pid 20470 exit signal Aborted (6)

Hi,
I have apache http server 2.4.51 installed on my VM running on OEL7.
In that apache logs intermittently getting signal abort error which is resulting error 500 for client .
Checking in apache error logs can see below,where as in apache access logs no entry of 500 is found

Hi @anandtripathi,

seems to be a bug in SiteMinder Agent. Do you have tried to update it?

Hi ,
Thank you for update

I have tried reaching out siteminder team, but they are saying this error not related to siteminder. But we also don't have any way to prove this error is definitely from siteminder and because of that signal is being aborted

Could be as well a crashing apache process.
https://bz.apache.org/bugzilla/show_bug.cgi?id=63670
Did it leave a core file behind?

To revive a famous quote from the 1960s: "Well, he would say that, wouldn't he?". It even exists as an acronym -- MRDA.

that's a typical C++, not a C message (due to the :: and _S_). AFAIK apache2 source is C, not C++. So I would assume that the error is SiteMinder related and not apache2 related.
apache2 is calling SiteMinder, not vice versa. So Siteminder has to ensure that each call to it has to be handled properly (i.e not with a core dump or signal failure).

@anandtripathi , you/your admins should reach out to siteminder tech support.

As @bendingrodriguez says, apache http server is written in C https://en.wikipedia.org/wiki/Apache_HTTP_Server, the errors thrown are definitely c++ in origin, https://en.cppreference.com/w/cpp/error/logic_error

i think need to enable some configuration to capture coredump, by default can't see any core dump or crash logs available on server where apache is installed and running
