ServerMaxFilters parameter.
Settings of filtering processes
FilterMaxMessages=10...1000 – maximum number of messages that can
be processed by a filtering process. Having processed the specified
number of messages, the filtering processes is finished. The default
value is 300.
The maximum number of messages that can be processed
by a certain filtering process is a random number selected by
the application from the range [FilterMaxMessages;
FilterMaxMessages + (FilterRandMessages–1)]. This
option allows you to avoid simultaneous ends and starts of a
great number of new filtering processes during peak loads on
the server.
FilterRandMessages=0...50 – value used to define the maximum number
of messages that can be processed by a certain filtering process.
FilterMaxIdle=30...3600 – maximum time (in seconds), during which a
filtering process can be idle. If a filtering process does not receive any
message for processing during the specified time, this process is
ended. The default value is 300.
FilterDelayedExit=0...30 – maximum time (in seconds) for which stopping a
filtering process can be delayed after the command to stop the process
is received. If the value of this option differs from zero, after the signal is
received, the filtering process will be stopped during the time, which is a
random number from the range [0; (FilterDelayedExit–1)]. The default
value is 0.
FilterDataTimeout=10...100 – timeout (in seconds) during which the filtering
process waits for the data from the client module. If the filtering process
receives no data during the specified time interval, message processing
is stopped. The default value is 30.
FilterLicenseConnectTimeout=1..10 – timeout (in seconds) during which
the filtering process can connect to the licensing module (kas-license) to
check the compliance of the request for processing with the license
terms. The default value is 2.
