I am running a configuration with 4 MX-SINIX5.24/NSC.
On one machine a dabtabase is runnging (ORACLE). 
The userinterface are SQLFORMS30-Masks which access via
SQLNET to the database.
On my backend - machine I am running out of memory therefore
the machine starts paging/swapping a lot.
Yesterday I had the problem that the machine had a 
system load of 90% ( 8 CPU ). 
After analyzing the system with TRACEX(a kernel trace-utility)
I found out that all the ORACLE-Backend processes approx. 80
made many of the following system-calls.
The interval for the listed number is 159 sec.

   sigvec   approx. 5000-6000
   sigsetmask  approx. 1600-1800
   sigblock  approx. 700
   sigpause   approx. 600

As I have no idea in understainding this values in terms of figuring out
if these are vlues that showing a synchronizationb problem ( TCP/IP,
acessing ALM-shared memory ...)  I would need the
help of a wizard.
THANKS
