[Comment 3 Benedikt Böhm (RETIRED) 2005-07-14 11:54:11 UTC]

why is this a vserver issue? 

[Comment 4 Michael Stewart (vericgar) (RETIRED) 2005-09-17 19:36:30 UTC]

Is anyone able to reproduce this bug?

[Comment 5 Robert Wolf 2006-05-30 00:18:00 UTC]

Hello. I have the same problem. When logrotate is started at about 3:00 a.m., it does postrotate script, which is /etc/init.d/apache reload, and then I cannot connect to apache. In the log, there is 

[Tue May 30 03:10:06 2006] [notice] seg fault or similar nasty error detected in the parent process

I have Server: Apache/2.0.55, Interface: mod_ssl/2.0.55, Library: OpenSSL/0.9.7i from ebuild version 2.0.55-r1.

Wow, now I found this bug is old, but I found this problem maybe a few months ago.

[Comment 7 Michael Stewart (vericgar) (RETIRED) 2006-06-26 09:25:56 UTC]

No one is able to reproduce this.
