Fixed In Version:	389-ds-base-1.3.3.1-19.el7_1
Doc Type:	Bug Fix
Doc Text:	Issue 1. Cause: Asynchronous simple paged results search request code was not thread safe. Consequence: There was a small window that the simple paged result slot was conflicted and it could crash the server. Fix: The code is now thread safe. Result: No more crash is observed. Issue 2. Cause: Abandoning simple paged results request was not handled correctly if an abandon is issued too quickly. Consequence: An internal search result object had a chance not to be released. Fix: At any timing an abandon request is issued, the search result request is safely released. Result: No more memory leak is observed.

Comment 6 Sankar Ramalingam 2015-06-29 08:35:02 EDT

1. No regression in simplepaged and filter acceptance tests
SIMPLEPAGED startup 	100% (1/1) 	  	 
SIMPLEPAGED run 	100% (17/17) 	  	 
SIMPLEPAGED cleanup 	100% (1/1)

filter startup 	100% (1/1) 	  	 
filter run 	100% (273/273) 	  	 
filter cleanup 	100% (2/2)

2. Proceeding with asynchronous simplepaged results.

Thank you so much for the valgrind output, Sankar.  It was very helpful.

Could you please try this scratch build with valgrind and see it changes the behaviour or not?

Thanks!

I copied builds from the above brew link and updated them in the same machine. Then, I created a new instance and ran the same tests with valgrind. I will update the bug after few hours.
Instance port: 19589

Stressed the server with the simplepaged search and I observed No crash. hence, marking the bug as Verified.
