Zend_Search_Lucene“在第0行的Unknown中没有堆栈帧抛出异常”

I get this error randomly when using Zend_Search_Lucene.

Exception thrown without a stack frame in Unknown on line 0

Has anybody ran into this who can help?

Thank you.

Zend_Search_Lucene commits data within destructor.

Static variables are destructed later and exception handling engine may be already unloaded.

Use $index->commmit(); before end of script.
