cpu usage - mssql Production DB server hitting 100% CPU -


i have mssql database server infrequently hits 100% cpu usage. when occurs no more connections can made database.

the solution have had far reboot server. not occur using type of frequency. not @ same time, day anything. went 3 weeks without happening, , far been week since happened last time experienced problem.

when review sql server errors logs can see pid appears causing issue, logs dont store process doing, being blocked process etc.

when issue has occured cannot connect box cannot run of sp_who commands try , identify sql statement being executed when issue occurs. admit trying connect using management studio.

we not want run sql profiler, on db box if can avoid because of resource drain happening infrequently.

am missing trick in there being recorded in error logs, because not dba, missing it.

  • there should statics shlould updated.
  • index fragmentation should check , reogarnize or rebuild sholud done.
  • try search complete in covering indexes.
  • find out missing indexes , implemet.
  • remove unused indexes.
