Bug #: 14745
Summary: probe timer.profile registration error
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: dyninst
AssignedTo: systemtap@sourceware.org
ReportedBy: shiziwen@gmail.com
Classification: Unclassified
Hi ，
When I run the stap command as below,
/opt/systemtap/bin/stap --ldd -d /usr/local/nginx/sbin/nginx
--all-modules -D MAXMAPENTRIES=5120 -D MAXACTION=20000 -D
MAXTRACE=50 -D MAXSTRINGLEN=1024 -D MAXBACKTRACE=100 -x 25017 a.stp
--vp 00001 > a.out
There is an error:
WARNING: missing unwind/symbol data for module
'stap_97bdcbebec34bca89d728c7b361aa64_24788'
WARNING: missing unwind/symbol data for module 'uprobes'
Pass 5: starting run.
ERROR: probe timer.profile registration error (rc -16)
The stap file as:
global s;
global quit = 0;
probe timer.profile {
if (pid() == target()) {
if (quit) {
foreach (i in s-) {
print_ustack(i);
printf("\t%d\n", @count(s[i]));
}
exit()
} else {
s[ubacktrace()] <<< 1;
}
}
}
probe timer.s(20) {
quit = 1
}
Can you help me find what happened and what should I do to resolve it?
Thanks very much.

errno -16 (EBUSY) is normal for concurrently used timer.profile event sources.
