Title: Smartping: Fixed "no buffer space available" error when having a lot of hosts configured
Component: cmc
Level: 2
Class: Bug fix
Version: 1.2.7i1
We already changed the way smartping was operating some time ago, this solved the
"no buffer space available" problem for many systems and increased the possible
number of hosts to be pinged dramatically.
This did not fix the problem for all systems. Some systems with maybe slower network
cards or drivers still had the problem that the message "no buffer space available"
appeared from time to time in the cmc.log. This occured when the cmc was asking for
ping requests faster than the kernel / NIC could process them. The send queue of the
single raw socket was filling up to the maximum and then resulting in this error message.
The icmpsender now opens 8 sockets instead of 1 for sending the ICMP requests.
Additionally the socktes now get a larger send buffer to make it less likely to fill up.

Title: Timeouts are now handled like classic SNMP implementation
Component: inline-snmp
Level: 2
Class: Bug fix
Version: 1.2.6b1
Timeouts of walks/bulkwalks of Inline-SNMP are now handled equal
to classic SNMP implementation. When a timeout occurs for the
configured X SNMP retries after Y SNMP timeouts (configured via
SNMP Timing Options), the whole "Check_MK" service is terminated
assuming that the host is not available.

Title: Suggesting "time" package, used for mk-job, in debian packages
Component: agents
Level: 1
Class: Bug fix
Version: 1.2.6b1
When not present, mkjob simply does not work. So if you like to use
mk-job, you need to have the "time" command available, which is
packaged in the "time" package on debain systems.

Title: Check_MK Discovery retry interval default value equals to the normal check interval
Component: config
Level: 1
Class: Bug fix
Version: 1.2.6b1
Before the retry interval always defaulted to 60 seconds when using the microcore which
could lead into unintended load when many discovery services are in a problematic state.
