Sigenable and Siginhibit System Calls

Hello,

I've upgraded from HP-UX 10.20 to HP-UX 11.00 an K460, and i encountered some Perf problems.
A process, which is usually running well on a production server, don't work very well now...
When i look precisely with Glance Plus what system calls it is running, most of all system calls are "sigenable" and "siginhibit". What does it mean ?
Thanks for your help...
PJA.

HI,

In database applications these routines are used to surround critical sections of code and to make them immune to interrupts until that section of code is completed. These are normally small sections of code that complete very quickly. A large number of these calls is not surprising.

If it ain't broke, I can fix that.
