Excessive sigsetstatemask system calls on hp-ux 11.23
I have 2 hp-ux 11.23 Itanium servers, both running Sybase ASE 12.5 64-bit. Using glance, I noticed that my development server's system CPU Utilization is quite a bit higher than the production server. The top processes are the sybase dataserver processes. The ONLY difference I see between the 2 systems is that on my development server, the dataserver has a much higher system call rate for the sigsetstatemask system call. Any ideas? I can't even find any information on this system call.

Hi MinhNg
From hits on the internet I see that sigsetstatemask is an application system call, but no where does it appear in any of the half dozen listed system call documents for hp-ux. If you refer to this link then you can verify my search.

This is something that is going to be coming from and application.

Michael,
Yeah, I was starting to think it's not an HP-UX system call. I will have to see what I can find on it in terms of Sybase. Thanks.
