Primary UBC Parameters:
numtcpsock The number of TCP sockets (PF_INET family, SOCK_STREAM type). This parameter limits the number of TCP connections and, thus, the number of clients the server application can handle in parallel.
numothersock The number of sockets other than TCP ones. Local (UNIX-domain) sockets are used for communications inside the system. UDP sockets are used, for example, for Domain Name Service (DNS) queries. UDP and other sockets may also be used in some very specialised applications (SNMP agents and others).
vmguarpages The memory allocation guarantee, in pages. 1&1 Virtual Server applications are guaranteed to be able to allocate additional memory so long as the amount of memory accounted as privvmpages (see the auxiliary parameters) does not exceed the configured barrier of the vmguarpages parameter. Above the barrier, additional memory allocation is not guaranteed and may fail in case of overall memory shortage.
avnumproc The average number of processes and threads.
Please note:
For the Virtuozzo 64-bit version for IA-64 processors, it takes four times more the size of the kernel memory than that for the Virtuozzo 32-bit version to handle one and the same process.
Secondary Parameters:
tcpsndbuf The total size of send buffers for TCP sockets, i.e. the amount of kernel memory allocated for the data sent from an application to a TCP socket, but not acknowledged by the remote side yet.
tcprcvbuf The total size of receive buffers for TCP sockets, i.e. the amount of kernel memory allocated for the data received from the remote side, but not read by the local application yet.
othersockbuf The total size of UNIX-domain socket buffers, UDP, and other datagram protocol send buffers.
dgramrcvbuf The total size of receive buffers of UDP and other datagram protocols.
oomguarpages The out-of-memory guarantee, in pages. Any 1&1 Virtual Server process will not be killed even in case of heavy memory shortage if the current memory consumption (including both physical memory and swap) does not reach the oomguarpages barrier.
Please note:
It is not possible to install a different or reconfigure the used kernel on our 1&1 Virtual Server Linux. Our accounts are based on Parallels Virtuozzo Containers which creates Virtual Environments using the underlying host machine's kernel.
