Error description
When running the SitemapGenerate scheduler job a transaction time out may be seen if there are a large number of products under one specific category. You may see something like the following in the SystemOut log files: [10/23/13 22:05:48:408 CDT] 00000008 TimeoutManage I WTRN0124I: When the timeout occurred the thread with which the transaction is, or was most recently, associated was Thread[WorkManager.default : 28,5,reserved: WC_WC_QA_Inst].

Local fix
Redistribute your products under multiple categories
Problem summary
USERS AFFECTED: WebSphere Commerce users on v7.0 running the SitemapGenerate job with a large number of products under one category PROBLEM ABSTRACT: Transactions time out while running the SitemapGenerate scheduler job BUSINESS IMPACT: The SitemapGenerate job will not create product URLs in the sitemap.xml file for the products under the category RECOMMENDATION:
Problem conclusion
The SitemapGenerate scheduler job uses the CatalogNodeListDataBean to to query information about products in each category. When the query returns more than 1000 rows, the query is executed multiple times, once for each 1000 rows. When the query returns many rows, the query is executed many times, which can lead to poor performance. However, it is not necessary to execute the query multiple times. This iFix changes the processing logic so that the query is only executed once for each category. It also changes the query to use parameter markers, which can improve performance. ------------------------------------------------------------- The latest available maintenance information can be obtained from the Recommended Fixes for WebSphere Commerce technote: http://www.ibm.com/support/docview.wss?rs=3046&uid=swg21261296
