We have just migrated our current IBM Websphere server , Oracle,Jasper 1.2.7, Java1.4 to Tomcat,MySql,Java 1.6 and Jasper 1.2.7 environment. But in production server we are seeing when thunderstone search crawler is crawling report urls, the threads are getting piled up and killing server. Please suggest settings? We tried changing below values, but no luck.
Max Process Size 50 MB to Unlimited
Max Threads 200 to 400
Timeout : 300 to 600
