RHBA-2009:0309 - Bug Fix Advisory

标题

An updated strace package that fixes a bug is now available.

描述

The strace program intercepts and records the system calls that are made
and the signals that are received by processes.

This updated strace package fixes a bug which occurred when "strace -f" was
used to trace a multithreaded program. strace selected threads to trace in
an inoptimal manner, which could have caused certain threads to either run
more slowly or to perpetually wait. With this update, strace selects
threads to trace in a smarter manner, thus ensuring that no threads are
left overlong in a waiting state, and therefore resolving the issue.

All users of strace are advised to upgrade to this updated package, which
resolves this issue.

解决方案
