tusc output

[SSP_1]

Hi Experts,

I am getting following output when I run tusc on hpux11.11 server. Process belongs to OID-LDAP and it's the one who is eating more cpu share. Could anyone having idea what does these system calls mean?

root@kansas:>./tusc -a 14098

Hi can you do a longer tusc run, say 10 seconds.

tusc -a (pid) >/tmp/tusc.out


and then attach that file.

Hi

What could be usefull here are some additional parameters for tusc:
1) If it is multithreaded:
-u or -l
(identify the thread for each entry - the difference between these shouldn't be very important)
2) -E
Print an entry when the function is called, not only when it returns (yes, it'll double the log size).
3) -T %T
Prints timestamp in notation specified by template (arguments like for function strftime() - see man strftime).
I'm curious how long does it take for another message to arrive.

Good luck
Adam
