I believe bug #11742 is causing one of our services from working correctly. In the bug report, it says a workaround is to disable checksums on the client. I checked all clients and checksum_pages are "0" (disabled). However, our application returns a MMAP error code. Could these two possibly be related? -- Jeremy Mann jeremy at biochem.uthscsa.edu University of Texas Health Science Center Bioinformatics Core Facility http://www.bioinformatics.uthscsa.edu Phone: (210) 567-2672
