Hi Alessio,


Here is an example where there are 2 spamdyke process (22218 and 22957) at
100%CPU:
The protocol is UDP, could be a DNS problem?

maybe. What does strace show you?


Strace show nothing:

[root@srv-2 ~]# strace -fftt -s  -o outputfile -p 11158
Process 11158 attached
^CProcess 11158 detached

[root@srv-2 ~]# ls -l outputfile.11158
-rw-r--r-- 1 root root 0  8 gen 16:12 outputfile.11158

:-(

[spamdyke-users] spamdyke processes at 100%CPU

2020-01-08 Thread Alessio Cecchi via spamdyke-users 

Hi,

in the last months I have an issue on some servers where spamdyke 
processes use the 100% of the CPU when connections are coming from 
specific remote host. When this happens the load on the server increase 
and the only way to solve is to kill the processes. We are running 
spamdyke 5.0.1 on CentOS 6.10.


Here is an example where there are 2 spamdyke process (22218 and 22957) 
at 100%CPU:
