php cgi stopped working after upgrade to plesk 11.5.30

[Linulex]

I have (had) a working 11.0.9
centos 6 64 bit
php = atomic 5.3.25

all 3 php types worked fine. module, cgi and fastcgi

after the update to 11.5.30 only module and fastcgi still work.
if i put php to cgi i get an internal error 500 and it wont load any module with these errors in the log

....

i have checked suexec and that works fine. checked the rights and tested it with a perl script.
allowed_memory is at 512M in php ini.
I have tried raising allowed_memory, even up to 14096M but still nothing.

I have checked suexec en directories as suggested in http://forum.parallels.com/showthread.php?263654-Premature-end-of-script-headers-cgi_wrapper

Anyone any ideas where to look?

thanks in advance

Is it Virtuozzo Container of any other VPS? Perhaps it is related to lack of resources. Check failcounters at least if it is Virtuozzo Container.

No, its a dedicated server with 32GB memory.

It was working fine in plesk 11.0.9 and it doesn't anymore after the upgrade to 11.5.30
