High sys_call_rate but all else normal ??

Hello;

I have a 11.31 system suddenly exhibiting a jump in the GBL_SYS_CALL_RATE in ovpa but all other stats look normal..
Traditional thinking is that this is caused by Apps code change
but our DEV team said none was implemented.
Normally one would expect to find corresponding increase in parms such as GBL_SYS_UTIL or disk I/O, etc..
Fo a while, GBL_PRI_QUEUE jumped but now its in normal range ..

Also checked PROC/File system Table usage and they are within normal range as well..


I am out of ideas ..
Anyone w/ fresh ones, most welcome ..

Thank you

With all statistics, it helps to see the actual figures and to get a feel for the scale of the system. I have seen a near-idle system give very strange statistics just because it was running HP OpenView software.

What's the scale of this system?

If you have glance, first look for looping processes.

Thank you Methyl ..

A bit dense here, when you say looping procs, do you mean run-away procs ??

If not, how do you identify them ??

Thnx again
