Hi,
I know this is a known issue. Once a browser connects to gsad, the daemon eats
all CPU.
What I do not understand:
~# ps x | grep gsad
23037 ? Sl 31:38 /usr/sbin/gsad --listen=0.0.0.0 --port=9392
--mlisten=127.0.0.1 --mport=9390
~# strace -p 23037
Process 23037 attached
select(0, NULL, NULL, NULL, NULL
(Nothing more)
~# strace -f -p 23037
Process 23037 attached with 24 threads

(repeated endless)
What I do not understand:
The children’s PIDs are decreased from 23120 to 23056 and then all starts again
with 23120. Why that?
Then:

lrwxrwxrwx 1 root root 0 Sep 13 19:17 ./23037/task/23120/exe -> /usr/sbin/gsad
Does that mean that PID 2307 has 23 threads, all pointing back to gsad?
