Hey guys,
Is this an OsTicket problem or MBString extension?
They just release a new version of the ticket system and it still made my apache crash with the same
php_mbstring.dll error.
Thanks.

By the way, this is the ticket with osTicket.

I doubled the ThreadStackSize to 131072 and it still crashed, it worked a little better though.
I opened a ticket with osTicket, they also asked me to add this to the directory where osTicket was
installed and nothing.
php_admin_value mbstring.func_overload 0

The exception happens already when installing and is a stack overflow in PCRE. This is a usual thing
with PCRE when too much recursion is caused. I don't think there's something to do about
this right now, maybe trying to upgrade to PCRE 8.37 . But I guess it's a good thing anyway
anyway to file a ticket for osTicket :) ... the arguments for the preg_split call are:

There could be also an mbstring issue as you say, but ATM i don't come through to it.
What you could also try is increasing the stack size for your Apache binary, then lets see further.
Thanks.

I forgot to include that I downloaded the open source version of osTicket version 1.9.7

I just added my httpd.conf and httpd-vhosts.conf so you can check it out, only domain has been
changed.
