warning::process-tracking - process-tracking facilities are not available
These errors and warnings occur when the kernel systemtap is running on lacks support for user-space process tracking facilities. COMPILE-TIME ERROR The error ERROR: user-space process-tracking facilities not available occurs when the script contains a uprobes probe point that the current kernel does not support. RUNTIME WARNINGS The warning, WARNING: process-tracking facilities are not available in this kernel and the related message, WARNING: cannot track target in process '...' both occur at runtime when running on a kernel (generally an older version) that has neither utrace functionality nor an acceptable substitute. The script should still load and run. However, probes that rely on availability of process-tracking facilities will silently fail to trigger.
RESOLVING THE ISSUE
If process-tracking functionality is absolutely necessary, either a kernel version newer than 3.5 is needed, or an older version must be compiled with appropriate utrace patches.
