Is xcache supported with osTticket? I've installed php5-xcache on my dev appliance because of Bolt CMS and osTicket have problem with Apache2: AH00052: child pid XXXX exit signal Segmentation fault (11)Apache/2.4.10 (Debian)PHP 5.6.28-0+deb8u1php5-xcache (3.2.0-1)osTicket v1.10 (901e5ea)AFAIK xcache can't be disabled per site, it was my first thought how to solve this problem.
