[Kroupware] Seg Fault during installation

[Stephan Buys]

Hi Bill,

Ok. Had a closer look at your strace. The segfault occurs after:

socket(PF_UNIX, SOCK_STREAM, 0)         = 12

Now according to /usr/include/asm/errno.h that return value means
that the is no memory. 

#define·ENOMEM· ·       12·     /* Out of memory */

Is this possible? Are you running on a small swap file or possibly running
out of memory? Maybe you dont have a swap partition and your disk is
running our of space?

Regards,
Stephan
