¶ LDAP的内存泄露

2006-03-17 17:00

故事:

友人在折腾LDAP ,使用Python 的 Twisted 组件来开发时应用常常死亡，怀疑Python的内存泄露，但是找不到证据……

结局:

找到高人delphj 运用内存分析工具:

/usr/ports/devel/valgrind> cat pkg-descr
Valgrind is a system for debugging and profiling un*x programs. With the tools
that come with Valgrind, you can automatically detect many memory management
and threading bugs, avoiding hours of frustrating bug-hunting, making your
programs more stable. You can also perform detailed profiling, to speed up and
reduce memory use of your programs.

The Valgrind distribution includes five tools: two memory error detectors, a
thread error detector, a cache profiler and a heap profiler. Several other
tools have been built with Valgrind.

Valgrind was ported to FreeBSD by Doug Rabson (http://www.rabson.org/).

才发现是LDAP本身的问题：每次RPC 的远程连接结束后，会泄露 32字节的内存！晕哪！怪不得叫 LDAP, 因为很轻的连接情况下的确很不容易发觉，在当前内存动不动就上Gb的情况下…………

Python的虚拟机是非常坚固的！不要轻易怀疑吧……
