I get "Out of memory!" error when try to make Plesk dump using Backup Utilities on my FreeBSD server, however, there is enough free memory in the system.

RESOLUTION



Mostly, the problem is not related to the amount of available memory in the system. By default, FreeBSD 4.x kernel is compiled with 'datasize' 512MB . See:

# limits -d
Resource limits (current):
datasize 524288 kb

 You cannot increase this value without the kernel recompilation. It means that, by default,  a process cannot allocate more than 512 MB.

The possible solutions are:
1. Recompile the kernel with a larger datasize.
2. Dump not the whole server, but by paths. For example per 100 domains.

If the server is running FreeBSD 5.x you may change kern.maxdsiz value in the /boot/loader.conf:

kern.maxdsiz="1073741824"
