Bug ID: 23813
Summary: Make "too many pending warnings" more helpful
Product: systemtap
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: runtime
Assignee: systemtap at sourceware dot org
Reporter: agentzh at gmail dot com
Target Milestone: ---
Some times we only get something like below from stap:
```
WARNING: too many pending (warning) messages
ERROR: too many pending (error) messages
WARNING: /opt/stap-plus/bin/staprun exited with status: 1
Pass 5: run failed. [man error::pass5]
```
It's not helpful at all since we have no idea what messages are actually
flooding the control message buffers.
We should make stap output the first few and also the last few messages in the
current control buffer when it thinks that there are "too many". Otherwise
there is no way to debug things here.

Eigler <fche at redhat dot com> --- These messages are printed when the rate of the messages is so high that there wasn't room to store any more of them. Maybe the suggestion is to drop -earlier- ones rather than new ones? Not sure how easy that would be. -- You are receiving this mail because: You are the assignee for the bug. ^ permalink raw reply [flat|nested] 5+ messages in thread
