PDM workgroup lockup

Does anyone have issues with workgroup locking up all theusers when one user is checking in or running a search? We have 12users, approx. 1,300 projects and 45,000 files with minimalrevisions (less than one per file). We have limited our search to"document" generate report and have also turned off the "showselections in project manager" option. Both of those changes havehelped. The lockup lasts as long as it takes for the document tocheck in or search to complete, then works again(software does nothave to be shutdown and rebooted).

Any suggestions would be appreciated.
