After upgrading to LiteSpeed 8.0, 8.0.1 or 8.0.2 Fast Compression jobs appear to hang. Backups jobs are getting hung. Jobs may show the following status in SSMS:
PREEMPTIVE_OS_GETPROCADDRESS
In this instance a maintenance plan that backs up several databases is indeed ”hanging”.
The logs appear to show the engine crashing namely at the appending\processing of the lsm file.
ST116627 created with development to address the issue.
This is fixed in LiteSpeed version 8.0.3 and addressed in LiteSpeed version 8.1
