Summary: Spamc/Spamd Overload Failover
Product: Spamassassin
Version: unspecified
Platform: Other
OS/Version: other
Status: NEW
Severity: enhancement
Priority: P5
Component: spamc/spamd
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
I would like to see a modification in the behavior of spamc/spamd to allow clean
failover when a server overloads.
Suppose I have two spamd servers and I want to configure them so that Server A
gets all the filtering traffic under normal loads and if the load is high it
starts failing over to Server B.
The idea is if max-children is reached or if the server load levels get too
high, or perhaps the precentage of free memory gets too low then I want spamd to
close port 783 to allow the server to process what it is currently working on.
This will cleanly signal spamc clients that it is down so that spamc should try
the next server in the list. (using spamc -d ServerA,ServerB)
