------- Additional Comments From ankita at in dot ibm dot com 2008-04-14 12:44 -------
Systemtap version am using: Systemtap-20070411 (Latest April build)
elfutils-0.131 kernel: 2.6.24.4-rt4. I am seeing the following errors:
ERROR: probe overhead exceeded threshold
WARNING: Number of errors: 1, skipped probes: 10
As a workaround, I am now invoking the script using the following cmdline:
#stap -vvv xyz.stp -D MAXTRYLOCK=1000 -D MAXSKIPPED=40000 -D TRYLOCKDELAY=10000
Note that if TRYOCKDELAY is removed from the cmdline, the stap still throws the
error.
