Hallo,

I have a SUN/Solaris
(Output of "uname -a" is:
SunOS sun 5.6 Generic_105181-03 sun4u sparc SUNW,Ultra-5_10),

running
ORACLE 8.0.3. My problem is, that sometimes the Listener-Process eats more than 99% of CPU.
When I do a "lsnrctl stop" and "lsnrctl start" again, everything is fine.

Anyone knows, how this can happen?

Thx for any help!!
