hello,

which version of Linux are you using?
Code:
uname -a

I dont feel that Linux is the culprit. Instead db2sync seems to be. Try running db2sync on freebsd/windows and look for a change. If the same problem persists then file a bug . I feel the source code has been tweaked up with or the memory allocation messes up too much.

Hope this helps,
Regards,
Gaurav.

CPU 73% id , the db2sysc process is waiting something.

You'd better to check db2 logs first.

Last question, why not kill the db2sysc process when CPU go up to 100%? Normally you needn't reboot the server.
