Apache not restart after add too many domains

[JokaUK]

Hello,
when I add more than 300 domains to a user's account, apache does not restart.
Can someone help me please?
Thank you

Can you maybe provide more informations? For example is there any log or error message?

Hi,
the error log of HTTPD is:

[Tue May 29 10:49:24.889261 2018] [mpm_prefork:notice] [pid 16089] AH00170: caught SIGWINCH, shutting down gracefully
AH00015: Unable to open logs

~]# apachectl configtest
[Tue May 29 10:52:16.594648 2018] [so:warn] [pid 30058] AH01574: module ruid2_module is already loaded, skipping
Syntax OK




This is strange because if I add 296 domains apache restarts but if I add 297 domains it no longer works.

I've done the rebuild of the domains and apache still does not start.

Thank you
