(all of the OS and information about the GK is at the end of the email).
Hello,
The machine is a dual xeon 2.4 ghz, with hyperthreading disabled.
I am running gnugk 2.2.2, which is gatekeeping for about 3 or 4 cisco
gateways, and a couple Cisco CCMs. 99% of the time, everything is A-OK.
99% of the time, the system is not busy -- perhaps 1 to 10 calls per
minute.
However, we have a application that triggers a huge amount of inbound
calls, perhaps 10 to 30 per second, several times per week. It will
largely fill up several ISDN-PRIs for a period of about 10 to 25 minutes.
During this time, the gatekeeper does not crash; however, it does seem to
be entirely consumed handling setups and teardowns (many, many of these
calls are rejected due to capacity issues on the terminated gateway).
The config file running on the GK is pretty vanilla, with the exception
that there are about 1,950 RewriteE164 lines.
During this time CPU is pretty pegged at about 60% (which is across both
processors). I am making the assumption that gnugk is taking a
non-threaded approach and killing one CPU, and the other is doing god
knows what.
So, my questions:
a) should gnugk kill/bring to it's knees a dual xeon 2.4 with 10 to 30
setups/teardowns per second?
b) Am I missing something planly obvious?
The GK normally sits around at about 0 to 3% CPU with the above 99% normal
low load. However, when I sit at my desk and redial/hangup from an ip
phone 2 times a second, CPU rides up to about 8%. Does this sound right?
Seems that it shouldn't be _that_ busy doing this.
Any help appreciated.
