Is anybody able to reproduce this behavior?


Just for the records, the segfault seems to be caused by a bad patch.
So sorry for the noise...

Segfault on graceful reload with OCSP stapling enabled?

[Micha Lenk]

Hi all,

I am currently observing a httpd segfault that is triggered on my system 
by every second graceful reload (i.e. SIGUSR1).


Unfotunately I won't be able to trace this down before Monday, so this 
is merely a heads-up for those interested.

Is anybody able to reproduce this behavior?

This is my configuration:

SSLStaplingCache shmcb:cache/ocsp_cache(128000)
SSLUseStapling on
SSLStaplingResponderTimeout 5
SSLStaplingReturnResponderErrors off

Thanks in advance for any helpful comments...

Cheerds,
Micha

BTW: The backtrace looks like this (however, please note that this is a 
patched http 2.4.16, so line numbers might be off a bit):
