In the SQl server, a particular table called "MetaData". Third party engine will post a http request through tomcat. it accepts max thread as 150. Savings will happen in MetaData table which is around 8 million records. After 12 hours continuously posting, then one of the tomcat is freeze. Its not accepting any more connections from third party and not creating sql connections too. What kind of optimum configurations should i follow up in production machine ?
