mod_fcgid problem after migration

Hello!
I migrate to the new server from 12.04 to 14.04. I installed new server (VM machine) on vmware. I migrated all web pages no new server.
And now have problem with fcgid. In this example I try to install MODX and give this error

Code:

kernel: [286785.700869] php-cgi[24720]: segfault at 16 ip 00000000006fe0d1 sp 00007fffd21e3890 error 4 in php5-cgi[400000+7ee000]

For example I can not to install MODX for new client:

Code:

[Tue Mar 17 21:36:55.986027 2015] [fcgid:warn] [pid 24889] (104)Connection reset by peer: [client 1.1.1.1:52283] mod_fcgid: error reading data from FastCGI server, referer: http://www.domain.com/setup/index.php?action=summary
