Hi Gaurav,
Thanks for looking into this. We suspect this issue was caused by a long running "DROP DATABASE" command (running for approximately 30 minutes) followed by an attempt to "MOUNT" the same database while the DROP was still executing.
Looking at the details of 766107, does it sound like this could be the same issue? This one is difficult for me to reproduce internally because I am working with small VMs that do not have very large databases that take a long time to drop.
After finding that the "DROP DATABASE" was still running when our application tried to execute the "MOUNT" command, I didn't feel like this was an ASE bug (other than the error message wasn't particularly helpful):
14545: Cannot locate the logical page 0 for database 'dxuTvv69v1UvWYZuZ5_MLC', dbid=15, on the device 'AADU$799P929g429LurGvctP_0_dat'. The page on the device is logical page 0 for dbid 0.
If the message had said something like "database xyz in use" or "drop database xyz is in progress", we would have known right away what the issue was.
Thanks,
Neal
