My host tried to upgrade Debian 7 to 8. But this resulted in the following error:
child pid exit signal Segmentation fault (11)
There is no further information.
They had to restore the backup and go back to Debian 7.
Does anyone have a clue what the cause of this may be?
if we do a strace then we get the segfault in the logs. Through CLI we only got response if php was called on index.php. The process tries to approach something in the memory that it has no rights for. The kernel stops this and returns a segfault.
