Hi,
the recommended way to find the processes using nflocks is lsof.

There may be no problem. If may simply be that no file locks are in use.

Are you seeing any errors on the system that have caused you to belive that there is a problem present?

Hi Bhavin,

lsof will help you find the usage of nflocks.

If you do not have lsof, download it from this link,

http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/lsof-4.73/

Here is a link on how to use lsof to find the usage of nflocks.

The itrc doc id is KBRC00005697.

If you are running out on nflocks, you could see problem with any number of applications like lp, sendmail, oracle etc..

Hope this helps.

nflocks is a requirement for certain programs to keep other programs from corrupting data. The value does not use memory or I/O...it is just a set of flags. It must be larger than the maximum number that you will ever need. Just make sure that your version of Glance is up to date. When you patch the kernel, quite often, you need to patch Glance too or the numbers may not be accurate.
