I have SQL server 2008 running on a Dell Server with 8 processors and 24 Gb RAM. Every few weeks the third party applications receives an SQL timeout issues which freezes other users. I then have to restart the server to bring it back on line. I have been running PerfMon and notice that my batch requests/sec were on average less than 10. My database is only 160 Mg and at most 25-30 user connections. Processor usage is minimal. Page life expetancy is over 300. Page splits are at time double the batch request/sec. Other performance parameters seem ok. Network connection readings are good. I set the memory max of 20 Gb and concurrent connections to 100.

Why would the system timeout? Could this be an issue regarding the programmin?
